How many calories are needed to change 1 gram of ice from C to steam at 110 C?

Since the specific heat of steam is 0.48 cal/g-oC that means that 0.48 calories are needed to raise 1g up 1oC. Thus it would take 50 x 0.48 calories to raise 50g of steam 1oC and 10 x 50 x 0.48 = 240 cal to raise the temperature of the steam to 110oC.

How much heat is gained when water is 5kg?

Heat is a form of energy that is transferred from systems having high temperature to low temperature. Hence we require 1680 kJ of energy to heat 5 kg of water from $ 20^circ C $ to $ 100^circ C $ .

How much energy is needed to boil 100g water?

The change in temperature is (100°C – 27°C) = 73°C. Since the specific heat of water is 4.18J/g/°C we can calculate the amount of energy needed by the expression below. Energy required = 4.18 J/g/°C X 100g X 73°C = 30.514KJ.

How much energy does it take to heat 1 degree of water?

The specific heat capacity of water is 4 200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4 200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature.

What is the quantity of heat required to raise the temperature of 1 gram of water through 1c is called?

The measurement of heat is called calorimetry. The calorie or gram calorie is the quantity of heat required to raise the temperature of 1 gram of pure water 1°C.

How do you calculate the energy needed to melt something?

Key Takeaways: Heat of Fusion for Melting Ice
