Which of the following substances has the greater heat capacity?
a. 0.02 g of aluminum
b. 2.00 g of aluminum
c. 20.0 g of aluminum
d. 200 g of aluminum***
please correct me if im wrong
That is right
thx
You are correct! The correct option is d. 200 g of aluminum.
Heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. It is usually expressed in terms of grams or moles. In this case, we are comparing different masses of aluminum to determine which one has the greater heat capacity.
To calculate heat capacity, we use the formula:
Q = m * c * ΔT
Where:
Q = heat energy
m = mass of the substance
c = specific heat capacity of the substance
ΔT = change in temperature
Since we are comparing aluminum, we can assume that the specific heat capacity (c) remains constant regardless of the mass. Therefore, the greater the mass of aluminum, the greater the heat capacity.
In the given options, option d. 200 g of aluminum has the greatest mass, so it will have the greater heat capacity compared to the other options.
