kg/m³
If a material has a high specific heat capacity, what does this imply about its ability to change temperature?
It requires more heat to change its temperature.
It changes temperature very quickly.
It cannot change temperature at all.
It requires less heat to change its temperature.
What does the symbol ΔT represent in the equation Q = mcΔT?
mass
change in temperature
specific heat capacity
heat
Which of the following equations can be used to calculate the heat energy (Q) absorbed or released by a substance?
Q = m + cT
Q = mcΔT
Q = m/cT
Q = mc/T
According to the equation Q = mcΔT, which combination of properties will require the least amount of heat to change an object's temperature?
Smallest mass, smallest specific heat capacity, smallest change in temperature
Largest mass, largest specific heat capacity, largest change in temperature
Smallest mass, largest specific heat capacity, largest change in temperature
Largest mass, smallest specific heat capacity, largest change in temperature
What does the symbol "Q" represent in the equation Q = mcΔT?
heat
mass
specific heat capacity
change in temperature
What does specific heat capacity measure?
The amount of light an object reflects
The resistance of an object to changes in temperature
The electrical conductivity of a material
The mass of an object
Why is it harder to heat or cool substances with higher specific heat capacities?
They require less energy to change temperature
They require more energy to change temperature
They change temperature more quickly
They do not change temperature at all
If two substances are given the same amount of energy, which one will experience a smaller temperature change?
The one with lower specific heat capacity
The one with higher specific heat capacity
The one with a higher mass
The one with a lower mass
What is the specific heat capacity of water in J/g·°C?
4.18 J/g·°C
2.00 J/g·°C
1.00 J/g·°C
0.50 J/g·°C
