Question 109

The specific heat capacities of copper, lead, olive oil, and water are given in the table below:

SubstanceSpecific heat capacity (J kg−1 ∘C−1J\text{ kg}^{-1}\text{ }^\circ\text{C}^{-1}J kg−1 ∘C−1)
copper390
lead130
olive oil2000
water4200

2 kg of each metal is put into 5 kg of each liquid.

The starting temperature of each metal is 80∘C80^\circ\text{C}80∘C. The starting temperature of each liquid is 20∘C20^\circ\text{C}20∘C.

Which combination has the lowest final temperature at thermal equilibrium?

A

copper and olive oil

B

lead and olive oil

C

copper and water

D

lead and water
