When liquid water freezes into ice energy is absorbed or released or not involved?
Energy is released.
What are the three changes of state in which energy is absorbed?
Well, the most common ones would be solid to liquid; solid to gas; liquid to gas. Of course, any other valid change between the 15 or so different states of matter involve an energy absorption in one direction, and an energy emission in the opposite direction.
Which change in state requires that energy be added to the substance?
A phase change from solid to liquid requires energy .likewise a liquid will vaporise into the gaseous state after appropriate increase in energy.
Is energy required for a liquid to change into a gas?
Yes.
Why does it take so much energy to change a liquid to a solid?
You actually take away energy to turn a liquid into a solid.
During which three changes of state is energy absorbed?
cchemical change and energy change also the change of a gas to a liquid
What change phase is heat energy absorbed by a substance?
liquid to gas
How can a liquid expand without changing state?
A liquid can expand when thermal energy is absorbed which is known as thermal expansion, but the thermal energy is not enough to change the liquid's state. When there is enough thermal energy, the liquid may change to a gas if the particles move fast enough to escape the liquid or it may change to a solid if the thermal energy is released from the matter.
What phase change will the greatest amount of energy be absorbed by 1 gram of water?
The liquid to gas phase change will absorb the largest amount of heat energy.
When a solid turns to liquid energy is absorbed?
No, a liquid releases energy to its surroundings when it becomes a solid.
How can gas change back to liquid by condensation?
the vibrational energy of the molecules is absorbed in the form of heat by cooling. this brings the particles closer making them liquid.
What do you call the change in state of matter from a liquid to a gas?
Condensation
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 the the energy from the sun when it changes liquid water into water vapor?
Evaporation
When a substance changes from solid to a liquid?
It melts. Energy is absorbed.
What happens to energy when a liquid turns into gas?
When a substance is changing from liquid to gas, the energy, which is absorbed, causes the atoms (or molecules) to move at a higher rate of speed, so that they are not staying close together, like in the liquid state. So the absorbed energy increases the kinetic energy of the atoms (or molecules).
What is the heat of fusion for water is the amount of energy that must be absorbed for water to?
Melt.
