How much the temperature of a material is changed by heat energy depends?
It depends on the amount of material (its mass), on how much heat energy is added, and on the material's heat capacity.
When a system does work and no heat is added to the system its temperature?
remains constant From Rafaelrz. When a simple closed system does work and no heat is added, the temperature of the system will drop. This is because the work is done at the expense of his internal energy, which is thermal energy.
What is the difference beween heat energy and temperature?
Heat energy is "energy" and temperature is not "energy".
What is a measure of the energy of motion of particles in a substance?
Particle motion increases as energy (like heat) is added. The motion slows as energy leaves. Temperature is a measure of this change in particle motion.
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
Can thermal energy be added without an increase in temperature?
No, thermal energy is entirely energy added for heat.

Sometimes heat energy is added but the temperature stays the same when is this?
During a phase change.
Why does the temperature rise as heat is being added when only one phase exists?
I think that the temperature rises when heat is being added because all of the energy has nothing else to focus on so it changes the temperature. Also, adding heat would make the temperature rise.
What is the difference beween heat energy and temperature?
Heat energy is "energy" and temperature is not "energy".
As heat energy is added to a liquid do the particles increase or decrease in movement?
As heat energy is supplied to a liquid, its temperature rises. The rise of temperature causes a rise in the kinetic energy of the particles; which happens when the speed of the particles increases.
Why does evaporation require that heat energy be added to a substance?
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's temperature)
How is heating related to a substance's temperature?
As an object is heated, the rate of increase in temperature is proportional to the rate of heat added. The proportionality is called the heat capacity. Because the heat capacity is actually a function of temperature in real materials, the total amount of energy added will be equal to the integral of the heat capacity function over the interval from the initial temperature to the final temperature. If you just assume an average heat capacity over the temperature range, then the rise in temperature will be exactly proportional to the amount of heat added.
Is heat the same thing as steam?
No. Steam is warm water vapor. Heat is added or external energy that causes a rise in temperature.

What metal is the highest final temperature after the heat energy has been added?
The metal with the lowest thermal capacity.
