Question

How much heat is required to raise 1 gram of copper at 1'C?

• A. 0.385 Joules
• B. 0.485 Joules
• C. 1.02 Joules
• D. 2.045 Joules

Answer 1

The correct option is A 0.385 Joules

The amount of heat $Q$ required to mass $m$ of a substance to raise its temperature through $\Delta t$ is given by:

$Q=mc\Delta t$

where $c=$ specific heat of substance

given $m=1g,\Delta t=1^{o}C$ and we have $c=0.385J/g{-}^{o}C$ (for copper)

Hence, $Q=1\times 0.385\times 1=0.385J$
