Question

Copper has a specific heat of 0.386 J/g°C. How much heat is required to increase 5.00 g of copper from 0.0°C to 10.0°C?
A.3.86 J
B.5.00 J
C.10.0 J
D.19.3 J

Answer 1

The correct answer is D. 19.3 J

Answer 2

Answer: D 19.3 J

Explanation:

The heat required to increase the temperature of a substance is given by

$Q=mC_s \Delta T$

where

m is the mass of the substance

$C_s$ is the specific heat capacity of the substance

$\Delta T$ is the increase in temperature of the substance

In this problem, we have:

$m=5.0 g$

$C_s = 0.386 J/gC$

$\Delta T=10.0 C-0.0 C=10.0 C$

Substituting into the equation above, we find

$Q=(5.0 g)(0.386 J/gC)(10.0 C)=19.3 J$
