Substance A and substance B have the same mass. A has a specific
heat of 0.499J/g oC. B has a specific heat capacity of 4.184 J/g
oC. Which one gets hotter faster? Multiple Choice.
1) B because a higher specific heat means that it takes more
energy to raise the temperature of a substance.
2) B because a higher specific heat means that it takes less
energy to raise the temperature of a substance.
3) A because a lower specific...

A substance has a melting point of 20°C and a heat of fusion of
2.6×104 J/kg. The boiling point is 150°C and the heat of
vaporization is 5.2×104 J/kg at a pressure of 1.0 atm. The specific
heats for the solid, liquid, and gaseous phases are 600 J/(kg·K),
1000 J/(kg·K), and 400 J/(kg·K), respectively. The quantity of heat
required to raise the temperature of 3.0 kg of the substance from
3°C to 118°C, at a pressure of 1.0 atm, is...

energy would it take to raise...

Copper melts at 1085 °C. The specific heat of copper is
387 J/(kg· °C). The latent heat of fusion of copper is 20.7×104
J/kg. How much heat is needed to raise the temperature of 0.050 kg
of copper from 23 °C to molten copper at 1085
°C?

The following table lists the specific heat capacities of select
substances: Substance Specific heat capacity [J/(g⋅∘C)] silver
0.235, copper 0.385, iron 0.449, aluminum 0.903, ethanol 2.42,
water 4.184, Water (2430 g ), is heated until it just begins to
boil.
If the water absorbs 5.07×105 J of heat in the process, what was
the initial temperature of the water? Express your answer with the
appropriate units.

The specific heat of a substance varies with temperature
according to c = 0.98 + 0.74T +
0.037T2, with T in °C and c
in cal/g·K. Find the energy required to raise the temperature of
1.7 g of this substance from 8.0°C to 12°C.

1A: During a process, 28 J of heat are transferred into
a system, while the system itself does 14 J of work. What is the
change in the internal energy of the system?
__________ J
1B: If the
internal energy of an ideal gas increases by 170 J when 250 J of
work are done to compress it, how much heat is
released?
__________ J
1C: It takes
270 cal to raise the temperature of a metallic ring...
