If 1.45 L of water is initially at 25.0 °C, what is its temperature after absorption of 9.4 × 10−2 kWh of heat?

Solution 100P

Answer :

One widely-quoted value for the specific heat of water is " 4.187 kJ / kg K ", meaning 4,187 joules to change the temperature of 1 kg of water 1 Kelvin (or 1° C). -- To make it easy on ourselves, we assume without proof or discussion that the mass of our 1.45L of water is 1.45 kg.So it takes (4,187 x 1.45) = 6,071 joules to accomplish each °C that we...
