When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
What happens to a substance as its thermal energy increases?
if temperature changes that means there is thermal energy in a substance
Is energy faster or slower when water changes from a gas to a solid?
To condense a subject you must reduce temperature. Reducing the temperature of a substance reduces the amount of heat that the object has, which means less thermal energy. Thermal energy is the energy of molecular motion, so when you reduce it, molecular motion slows.
Has thermal energy been transfered into or out of a substance if the average kinetic energy changes?
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
What happens when a substance change states?
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
What happens to heat energy when a substance changes from solid to liquid?
it melts
When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
What happens to a substance as its thermal energy increases?
if temperature changes that means there is thermal energy in a substance
Which may be true for a substance that absorbs energy?
The energy decreases the molecular motion and the kinetic energy of the substance.
What is the thermal energy of a substance?
the total energy from molecular motion.
What is a thermal energy of a substance?
the total energy from molecular motion.
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
Increasing temperature means increased kinetic energy on the atomic or molecular level. Temperature of a given substance is the average kinetic energy of the particles of which that substance is composed.
What happens to the kinetic energy of the particles of a substance as the changes from a liquid to a gas?
in my opinion, I don't really know
What is a form of energy caused by increased molecular activity and is a measure of the total energy of the substance?
Kinetic energy is the measure of the total energy of a substance.
Is energy faster or slower when water changes from a gas to a solid?
To condense a subject you must reduce temperature. Reducing the temperature of a substance reduces the amount of heat that the object has, which means less thermal energy. Thermal energy is the energy of molecular motion, so when you reduce it, molecular motion slows.
