Suppose that we replace the aluminum with a mystery metal and repeat the experiment in the video. as in the video, the mass of the metal is the same as that of the water. room temperature is about 20 c before the start of the experiment. the water heats up to 40c, and the mystery metal heats up to 80c. compared to that of water, the heat capacity of our mystery metal is
a) three times greater.
b) one-third as great.
c) half as great.
d) two times greater.
e) the same.

Compared to that of water, the heat capacity of our mystery metal is:

b) one-third as great

Specific Heat Capacity is the amount of energy needed to raise temperature of 1 kg body for 1°C.

Q = Energy ( Joule )

m = Mass ( kg )

c = Specific Heat Capacity ( J / kg°C )

Δt = Change In Temperature ( °C )

Let us now tackle the problem!

Given:

room temperature = to = 20°C

final temperature of water = t_w = 40°C

final temperature of metal = t_m = 80°C

mass of water = mass of metal = m

Asked:

specific capacity of metal = c_m = ?

Solution:

Compared to that of water, the heat capacity of our mystery metal is:

b) one-third as great.
