Question

Glass has a specific heat of 0.84 J/g·°

c. Copper has a specific heat of 0.39 J/kg·°
c. Which material takes more energy to warm up?

Answer 1

The higher the specific heat capacity level, the more energy it requires to warm it up by 1°C.
Since the unit for the given numbers are different, simply multiply 0.84 by 1000 so that we can know the specific heat capacity of glass is 840 J/kg·°
Comparing both numbers, the value for glass is larger.
Therefore, glass requires more energy to warm up.

Answer 2

glass

Step-by-step explanation:

the specific heat capacity of any material is defined as the amount of energy needed to raise the temperature of a unit mass of that material by one degree Celsius

therefore, the higher the specific heat of the material the higher the required energy to increase its temperature.

glass has a higher specific heat capacity, it therefore would take more energy to warm up.
