Answer:
c. 10.0 J
Explanation:
The heat (Q) needed to increase the temperature of a certain mass of a sample can be calculated using the following expression:
Q = c . m . ΔT
where,
c is the heat capacity
m is the mass
ΔT is the change in temperature
Let's call Q₁ (5.0 J) the heat to increase the temperature of the mass m₁ by ΔT = 10.0°C.
Q₁ = c . m₁ . ΔT
If the mass is doubled (m₂ = 2 m₁), the heat required is:
Q₂ = c . m₂ . ΔT = c . 2 . m₁ . ΔT = 2 . c . m₁ . ΔT = 2 . Q₁
Q₂ = 2 . Q₁ = 2 . 5.0 J = 10.0 J
