Question 208

An object of mass m m\,m with specific heat capacity c c\,c absorbs thermal energy ΔE \Delta E\,ΔE without changing its state. Which of the following expressions correctly gives the temperature rise ΔT \Delta T\,ΔT of the object?

A

ΔT=ΔEmc\Delta T = \frac{\Delta E}{m c}ΔT=mcΔE​

B

ΔT=mcΔE\Delta T = \frac{m c}{\Delta E}ΔT=ΔEmc​

C

ΔT=ΔEcm\Delta T = \frac{\Delta E c}{m}ΔT=mΔEc​

D

ΔT=ΔEmc\Delta T = \frac{\Delta E m}{c}ΔT=cΔEm​
