Answer: C; it will also change from a gas to a liquid at 78°C while the gas loses energy.
Explanation:
Took the test. If it boils at 78°C, then that means it will be either a liquid turning into a gas, or a gas turning into a liquid. If the gas loses energy, that means it is being cooled, so if a gas loses energy at 78°C, it will become a liquid.
Answer:
Mass = 12.33 g
Explanation:
The expression for the calculation of the enthalpy change of a process is shown below as:-
Where,
is the enthalpy change
m is the mass
C is the specific heat capacity
is the temperature change
Thus, given that:-
Specific heat = 0.450 J/g°C
= 81.0 J
So,
<u>Mass = 12.33 g</u>
