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 means that is takes less energy to raise the temperature of a substance.

4) A because a lower specific means that is takes more energy to raise the temperature of a substance.

Homework Answers

Answer #1

Ans: 3) A because a lower specific heat means that it takes less energy to raise the temperature of a substance.

Specific heat is defined as the heat required to raise the temperature of 1 gram of substance by 1 degree Celsius.

A has specific heat of 0.499 J/g. °C where as B has a specific heat of 4.184 J/g.°C. A needs 0.499 Joules of heat to raise it's temperature by 1 degree Celsius whereas B needs much higher amount of 4.184 Joules. So A gets hotter faster than B.
