Question

Identify the equation used to determine the amount of heat required to melt 10 grams of ice.

• A. $Q=m{C}_{sp}△T$
• B. $Q=n△H$
• C. $KE=\frac{1}{2}m{v}^2$
• D. $PE=mgh$
• E. $PV=nRT$

Answer 1

The correct option is A $Q=m{C}_{sp}△T$

Option A is the correct answer.

To calculate the amount of heat required to melt a piece of ice, we need to know the mass of ice ($m$), the change in temperature ($\Delta T$), as we are raising the temperature. We also need to know the specific heat ($C_{sp}$). Thus the equation can be written as:

$Q$ $=$ $m$$C_{sp}$$\Delta T$
