which is non volatile course hero

What is the difference between volatile and non-volatile?

A non-volatile substance refers to a substance that does not readily evaporate into a gas under existing conditions. Non-volatile substances exhibit a low vapor pressure and a high boiling point. Sugar and salt are examples of non-volatile solutes. A volatile substance is one that evaporates or sublimates at room temperature or below.

What is the solution for non-volatile substances?

Solution = solvent + solute. A non-volatile substance refers to a substance that does not readily evaporate into a gas under existing conditions. Non-volatile substances exhibit a low vapor pressure and a high boiling point. Sugar and salt are examples of non-volatile solutes.

What is a volatile solution?

In fact, in volatile solutions, the parts of the solution can be so much alike that it takes a bit of time and effort to parse out which is the solute and the solvent. And if you have three or more ingredients in a solution, then it really gets hairy!

Which of the following is a volatile substance?

A volatile substance is one that evaporates or sublimates at room temperature or below. Volatile substances have higher vapor pressures versus non-volatile substances at the same temperature. Examples of volatile substances include alcohol, mercury, and gasoline.

What are the types of non-volatile?

There are mainly five types of nonvolatile memory technology: Flash memory, ferroelectric random-access memory (FeRAM), magnetic random-access memory (MRAM), phase-change memory (PCM), and RRAM.

Is ROM is non-volatile in nature?

Read-only memory is a non-volatile storage solution. This is because you cannot erase or modify it when the computer system is turned off.

Which of the following are examples of non-volatile storage?

Examples of Non-Volatile Memory ChipsRead-only memory (ROM)Erasable programmable ROM (EPROM)Electrically erasable programmable ROM (EEPROM)Ferroelectric RAM (FRAM)Flash memory (e.g., NOR and NAND flash memory and solid-state drives (SSD)Magnetic storage devices (e.g., hard disks, magnetic tape, floppy disks, etc.)More items...

Which devices are non-volatile in nature?

Examples of non-volatile memory include read-only memory ROM, flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

Which of the following is non-volatile?

non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

What is non-volatile ROM?

Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data.

Which of the following is non-volatile storage Mcq?

Which of the following is non-volatile storage? Explanation: The secondary storage is the non-volatile storage unit because the data is not lost when the power supply is dissipated. Primary memory is the volatile memory. 6.

Is ROM a non-volatile memory?

Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device.

What does non volatile mean?

Definition of nonvolatile : not volatile: such as. a : not vaporizing readily a nonvolatile solvent. b of a computer memory : retaining data when power is shut off.

What is volatile and non-volatile?

The volatile memory stores data and computer programs that the CPU may need in real-time, and it erases them once a user switches off the computer. Cache memory and RAM are types of Volatile memory. Non-volatile memory, on the other hand, is static. It remains in a computer even after a user switches it off.

What happens when you mix two volatile solutions?

When you have two volatile solutions together, they will push each other toward evaporation and have high vapor pressures and low boiling points. When you have a non-volatile solution, such as a sucrose or salt solution, you have an increasing boiling point as the concentration of sucrose or sugar increases.

What happens when you increase the temperature of a volatile substance?

Volatility, Temperature & Pressure. If you have a volatile substance, it will have a high vapor pressure and a low boiling point. An increase in temperature will cause an increase in vapor pressure, or the pressure at which the gas phase is in equilibrium with the liquid or solid phase.

What is Raoult's law?

Additionally, Raoult's law states that the partial water vapor of each component of an ideal mixture of liquids equals the vapor pressure of the pure component multiplied by the molar fraction of the mixture. Raoult's law is expressed by the vapor pressure equation: To unlock this lesson you must be a Study.com Member.

What is a solvent?

A solvent is something that a solute is dissolved into. For example, if you remember that water is the universal solvent, it will be easy to remember which part of a mixture is the solvent and that the solute is something like salt or sugar that is dissolved into it. Solution = solvent + solute. A non-volatile substance refers to a substance ...

Which substances have higher vapor pressures?

Volatile substances have higher vapor pressures versus non-volatile substances at the same temperature. Examples of volatile substances include alcohol, mercury, and gasoline. A good way to remember which substances are volatile and non-volatile is to think about which types of substances you readily smell.

Is sugar water a volatile substance?

Conversely, a volatile substance is one that evaporates easily.

What is the difference between volatile and non-volatile memory?

Below are the differences between volatile and non-volatile memory: 1. Volatile memory is the type of memory in which data is lost as it is powered-off. Non-volatile memory is the type of memory in which data remains stored even if it is powered-off. 2.

Is ROM volatile or nonvolatile?

ROM (Read Only Memory) is the most common example of non-volatile memory. It’s not economical and slow in fetch/store as compared to volatile memory however stores higher volume of data. All such information that needs to be stored for an extended amount of time is stored in non-volatile memory.
