How do you calculate the amount of energy needed to melt ice?

Using the equation for a change in temperature and the value for water from Table 1, we find that Q = mLf = (1.0 kg)(334 kJ/kg) = 334 kJ is the energy to melt a kilogram of ice. This is a lot of energy as it represents the same amount of energy needed to raise the temperature of 1 kg of liquid water from 0ºC to 79.8ºC.

How do you solve for C in a calorimeter?

Part I: Heat Capacity of the Calorimeter The heat capacity, C, of a substance is the amount of heat required to raise the temperature of a given quantity of the substance by 1 degree. The relationship between heat capacity and specific heat is C = m×sp_heat. Therefore, q = C×Δt and C = q ÷ Δt.

How many joules of energy are required to make 50 grams of ice at 0 ΟC completely melt?

The answer is 153.7kJ .

What is the mass of a calorimeter?

In more recent calorimeter designs, the whole bomb, pressurized with excess pure oxygen (typically at 30 atm) and containing a weighed mass of a sample (typically 1–1.5 g) and a small fixed amount of water (to saturate the internal atmosphere, thus ensuring that all water produced is liquid, and removing the need to …

How much energy does it take to melt 50g of ice at 0 C?

4000 cal is the amount of heat required to convert 50 grams of ice at 0 degree Celsius to water at 0 degrees Celsius.

How do you calculate the energy lost when melting ice?

You calculate the energy lost by the original water and by the calorimeter. Work out the total heat lost. This heat was gained by the ice. The ice goes through two steps – it melts to make water at 0 deg C and then this melted ice warms up to 25 deg C.

What happens when ice melts at 0 degrees Celsius?

While ice melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is 333 kJ/kg . Read till the end. All the ice won’t melt. Equilibrium will be established between ice and water.

How much heat does it take to melt an Ice Cube?

This can be calculated by: Heat needed to melt ice at 15ºC to 0ºC (still in solid state) Heat needed to melt solid ice at 0ºC to 0ºC liquid. This means that to melt a 0.015kg ice cube to water at 0ºC you will need 4520.7 J of heat.

What is the final state of ice at 0°C?

Heat released by water to reach from 80°C to 0°C = heat required by ice to melt into water at 0°C. So, the ice will melt to water and it’s temperature will be 0°C. Hence, the final state would be water at 0°C.
