How does the volume of matter change with an increase in temperature?

Answer 1

According to Charles law, V/T is constant (pressure). If the volume is doubled, the temperature of the system have to be doubled and vice versa. The volume of a rigid container does not change upon heating.

Answer 2

When you heat a gas you provide it thermal energy which raises its internal energy (the sum of all microscopic kinetic and potential energy of all the molecules) the molecules move with a higher value of kinetic energy which implies each molecule moves with a higher velocity than before..As the molecules collide with one another or with the walls of the container they are kept in they rebound with higher energies moreover intermolecular forces weaken and the molecules space out further which results in an increase in volume

Answer 3

In most cases, the volume will increase with temperature... density decreases.

The volume of liquids and gasses increase as they are heated. This is because the heat energy is tranferred to the particles in the substance, making them increase their speed. The particles then need more space to move, so there becomes more space around the gas or liquid particles causing the substance expand and take up more space.

Answer 4

Because the energy content of the object increased, and energy has mass. The world's most famous equation: E=m(C-squared) can be written m=E/(C-squared). E is the energy, m is the mass, and C is the speed of light. Adding energy adds mass. All of this has nothing to do with expansion, except of course, most things do expand when heated.

It takes 420,000 Joules of energy to heat kilogram of water from 0 to 100 degrees C (without turning it to steam). The extra mass is 0.000000004 gram, from the formula above.

Answer 5

it increase as a result of pressure generated from the heat

Answer 6

Molecules are moving or vibrating faster when they are heated.
