Temperature of Object
What scale is used by scientists to measure temperature
heat
At the freezing point, the particles of an object have no kinetic energy
False- absolute zero
What are the 2 factors that determine an object's thermal energy?
Temperature and number of particles
What is the measure of the average kinetic energy of the particles in an object?
Temperature
heat flow from a _________ object to a ______object until they are the same temperature.
warmer; cooler
Temperature is a measure of how hot or cold something is compared to its reference point.
true
The amount of thermal energy in an object depends on its ________ the number of particles in it, and how those particles are arranged.
temperature
Scale most used to measure temperature in the United States?
Fahrenheit
What happens when heat is added to a gas in a sealed container?
a. the particles of gas slow down
b. the particles of gas speed up
c. the motion of the particles does not change.
d. the particles of gas form a pile on the bottom of the container.
B.
When heat is absorbed by an object, the speed of the particles in the object is unchanged.
false; increases
The temperature 0℃ is equivalent to
32 degrees Fahrenheit
Scale used in most other countries to measure temperature?
Celsius
Object A is much larger Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is the same as the the thermal energy of Object B.
False; greater than
Temperature at which no more thermal energy can be removed from an object
Absolute Zero
On the Celsius temperature scale, there are no negative numbers.
false; kelvin
