1.
Two objects in thermal equilibrium have
equal thermal energy
equal mass
equal temperature
equal specific heat capacity
2.
The zeroth law states that if A is in thermal equilibrium with C, and B is in thermal equilibrium with C, then
A and B have different temperatures
A and B are in thermal equilibrium
A transfers energy to B
B is hotter than A
3.
A 0.20 kg block at 100 °C is placed in 0.50 kg of water at 20 °C; the final temperature is 24 °C. The specific heat capacity of the block is closest to (cwater = 4200 J kg−1 K−1)
110 J kg−1 K−1
390 J kg−1 K−1
550 J kg−1 K−1
2000 J kg−1 K−1
4.
Why must you wait before reading a thermometer in a liquid?
The liquid must reach boiling point
The thermometer must reach thermal equilibrium with the liquid
The liquid has to stop moving
The scale must be zeroed
5.
At thermal equilibrium between two objects in contact, the net energy transfer is
zero
from the larger to the smaller object
from the hotter to the colder
equal to their heat capacities
6.
Which is the best description of the zeroth law's importance?
It defines absolute zero
It states energy is conserved
It gives the efficiency of engines
It shows that temperature is a well-defined property that can be compared using a thermometer
