Answer to Question #86960 in Molecular Physics | Thermodynamics for Alex

Question

The specific heat capacity of ethanol is 2440J/kg °C. How many joules of energy will be required to heat 150g ethanol to 35°C if the starting temperature is 22°C?

Answer 1

$E = cm{\Delta}t = 2440\frac{\text{J}}{\text{kg}^\circ\text{C}}\times0.15~\text{kg}\times(35-22)^\circ\text{C} = 4758~\text{J}. \\$
