 # Quick Answer: Is Mass Dependent On Temperature?

## Which solution is the most concentrated?

A concentrated solution will contain the most solute molecules per solvent molecules.

Hence, option D) is most concentrated.

Q: The movement of water molecules through the plasma membrane is called ______….Which solution is most concentrated?A) Only I and IIB) Only I and IIIC) Only II and IIID) All I, II and III.

## Which has higher temperature 1 cup of boiling water or 1 teapot of boiling water?

Answer. Both the same temperature. If both are boiling water, they both must be at 100 degrees Celsius. The cup will come to boiling point faster than the teapot but still once they are both boiling both are at the same temp.

## Does mass affect heat transfer?

The mass difference between two objects causes heat transfer. The density difference between two objects causes heat transfer. The temperature difference between two systems causes heat transfer.

## Why Molality does not change with temperature?

Molality is then the number of moles of solute per kilogram of the SOLVENT, NOT solution! … That is because MOLALITY does not depend on temperature, (Neither number of moles of solute nor mass of solvent will be affected by changes of temperature.) while MOLARITY changes as temperature changes.

## What similarities and differences did you observe when a drop of dye was added to each container?

Answer Expert Verified -The dye mixes the fastest when dropped to the container having a hot water; the dye mixes slower when dropped to the container having tap water; and the dye mixes the slowest when dropped to the container having cold water.

## What is the difference between heat and temperature?

Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. … Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

## How is temperature difference calculated?

This is easy. You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C. For decreases in temperature, the result is negative.

## What is the molality of pure water?

55.510 mJust like there’s a real molar concentration for water by itself ( 55.348 M ), there is a real molality for water by itself ( 55.510 m ).

## Does volume increase with temperature?

These examples of the effect of temperature on the volume of a given amount of a confined gas at constant pressure are true in general: The volume increases as the temperature increases, and decreases as the temperature decreases.

## Is Mass percent temperature dependent?

Mass percentage,ppm,mole fraction and molality are solely dependant on mass which is independent of temperature.

## Does weight depend on temperature?

Yes. If you have absolutely identical objects that have the same weight exactly when they are at the same temperature, then when one object is heated, it will weigh more. … Temperature differences means that there is a different amount of kinetic energy in the motion of the atoms of the two bodies.

## What is the relationship between mass and temperature?

(a) The amount of heat transferred is directly proportional to the temperature change. To double the temperature change of a mass m, you need to add twice the heat. (b) The amount of heat transferred is also directly proportional to the mass.

## Does water volume change with temperature?

An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume. … When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.

## Does mass affect temperature?

If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature affects thermal energy, but temperature isn’t the same thing as thermal energy. That’s because an object’s mass also affects its thermal energy.

## Does mass or volume vary with temperature?

Density changes with temperature because volume changes with temperature. Density is mass divided by volume. As you heat something up, the volume usually increases because the faster moving molecules are further apart. Since volume is in the denominator, increasing the volume decreases the density.

## Which has more heat?

Answer: Boiling water has a lot more heat than the oven’s air (even though the air has a higher temperature).

## What is the lowest possible temperature?

Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion.

## Does volume change with temperature?

So, that means that volume is directly proportional to temperature. Even then, since we increase the temperature inside a material, the molecules’ kinetic energy increases and they start to vibrate more and move around further from each other, therefore accounting for an increase in volume.
