High Specific Heat
Low Specific Heat
It's solid
It's always cold
When heat is absorbed by a substance, what happens to the temperature of the substance?
it increases
it stays the same
it decreases
it depends on the substance
The melting point of a solid is 24.9 degrees Celsius. As heat is added to melt the solid, what happens to the particles?
Group of answer choices
the motion of the particles decreases and the distance between the particles increases
the motion of the particles decreases and the distance between the particles decreases
the motion of the particles increases and the distance between the particles decreases
the motion of the particles increases and the distance between the particles increases
Cold things often have a _________ kinetic energy because_______
lower; particles are moving around less
lower; particles are moving around more
higher; particles are moving around the same
higher; particles do not move
For objects that have the SAME mass, which object will have a HIGHER thermal energy?
the object with the higher temperature
the object with the lower temperature
the objects will have the same temperature
the objects have no temperature
You have two identical stuffed animals in your room. One in the shade and one in the direct sunlight of the window. What happens to the thermal energy of the two stuffed animals.
The one in the shade will have less thermal energy and the one in the sunlight will obtain more thermal energy.
More thermal shade, less thermal in the sunlight.
Both will have the same because they are identical having the same amount of mass.
The both will raise temperature and thermal energy about 15 degrees, just the one in the shade will take less time to reach the top temperature.
Which of the following would contain molecules with the greatest average kinetic energy?
Water vapor from your breath on a cold night.
A snow ball
Ice on a pond
A glass of hot coco
