## How many joules does it take to melt 50g of ice?

How many joules of heat are needed to melt 50 g of ice at 0°C and then warm the liquid to 65°C? heat of fusion of ice = 334 J/g specific heat of water = 4.184 J/g°C specific heat of ice = 2.03 J/g°C heat of vaporization of water = 2260J/g.

## How many joules of energy does it take to melt ice?

A total of 334 J of energy are required to melt 1 g of ice at 0°C, which is called the latent heat of melting.

**How many joules does it take to melt 20 grams of ice?**

The answer is (C) 6680 J .

### How do you calculate the energy needed to melt ice?

Let us look, for example, at how much energy is needed to melt a kilogram of ice at 0ºC to produce a kilogram of water at 0°C. 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.

### How much energy in joules does it take to melt 1kg of ice?

How many Joules of energy do you need to melt all the ice into a pure liquid along the path from B to C on the graph? Answer: For 1 kilogram of ice ,which equals 1000 grams, we need 333 Joules/gram x 1000 grams = 333,000 Joules.

**How many joules of energy are required to evaporate melt 100 grams of ice?**

The specific heat of melting of ice is 334 J/g, so melting 100g of ice will take 33,400 J.

## How many joules of energy does it take to melt ice at 0 degrees?

In water’s case, an enthalpy of fusion equal to 333.55 J g−1 tells you that 1 g of ice at 0∘C can be converted to 1 g of liquid water at 0∘C by supplying 333.55 J of heat.

## How much energy is needed to completely melt a 15 g of ice?

Therefore, energy needed to melt 15 grams of ice to water at 0∘C is 4520.7J.

**How much energy in joules does it take to melt 1 kg of ice How much energy in joules does it take to raise 1 kg of water by 50 OC which number is greater?**

How many Joules of energy do you need to melt all the ice into a pure liquid along the path from B to C on the graph? Answer: For 1 kilogram of ice ,which equals 1000 grams, we need 333 Joules/gram x 1000 grams = 333,000 Joules. Problem 3 – The Specific Heat of liquid water is 4180 Joules/kg C.

### How many joules does it take to melt 35 g of ice at 0?

11,678 J

We have to convert the heat into joules. 11.678 kJ = 11,678 J. – Therefore the amount of heat required in joules to melt the ice at 0oC is 11,678 joules.

### How many joules are required to evaporate 1g of boiling water?

For water at its normal boiling point of 100 ºC, the heat of vaporization is 2260 J g-1. This means that to convert 1 g of water at 100 ºC to 1 g of steam at 100 ºC, 2260 J of heat must be absorbed by the water.

**How many joules does it take to melt 35 grams of ice?**

It takes 12,000 Joules of energy to melt 35 grams of ice at 0 °C The enthalpy change for melting ice is called the entlaphy of fusion. Its value is 6.02 kj/mol. This means for every mole of ice we melt we must apply 6.02 kj of heat.

## How much heat do you need to melt ice?

The enthalpy change for melting ice is called the entlaphy of fusion. Its value is 6.02 kj/mol. This means for every mole of ice we melt we must apply 6.02 kj of heat. We can calculate the heat needed with the following equation:

## How to calculate heat of fusion of ice in joules per gram?

The Latent Heat of Fusion for ice is 384J/gram. So 10 grams of ice require: 10X384 = 3840J of energy. Next we need to raise the temperature of this water from 0°C to 20°C.

**How much energy does 10 grams of ice need?**

So 10 grams of ice require: 10X384 = 3840J of energy. Next we need to raise the temperature of this water from 0°C to 20°C. What does heat of fusion mean? Answer.
