How much heat energy is needed to raise the temperature of 5 kg of coal from 20c to 220c?

To calculate the heat energy needed to raise the temperature of a substance, you can use the formula Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. For coal, the specific heat capacity is typically around 0.24 J/g°C. Convert the mass from kg to g (1 kg = 1000g) and then plug the values into the formula to find the heat energy required.


How much heat is required to raise the temperature of a 30.0 g block of aluminum from 25.0ºC to 75.0ºC?

The specific heat capacity of aluminum is 0.897 J/g°C. The heat required can be calculated using the formula Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the values, you can calculate how much heat is required.


Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?

No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.


How much heat is required to convert 0.3 of ice at 0 to water at the same temperature?

The heat required to convert ice at 0°C to water at 0°C is known as the latent heat of fusion. For water, this value is 334 J/g. Therefore, to convert 0.3 g of ice to water at the same temperature, the heat required is 0.3 g * 334 J/g = 100.2 Joules.


How much heat is required to raise the temperature of 0.25 kg of water from 20 Celsius to 30 Celsius?

The specific heat capacity of water is 4186 J/kg*C. To calculate the heat required, use the formula: heat = mass * specific heat capacity * change in temperature. Plugging in the values, the heat required to raise the temperature of 0.25 kg of water by 10 degrees Celsius is approximately 1046.5 Joules.

If 30.86g of H2O is frozen (from liquid to solid) how much heat energy is required?

No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.


How much heat energy is required to raise the temperature of 0.365 of copper from 23.0 to 60.0 The specific heat of copper is 0.0920?

To calculate the heat energy required, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of the copper (0.365 kg), c is the specific heat capacity of copper (0.0920 J/g°C), and ΔT is the change in temperature (60.0°C - 23.0°C). First, convert the mass to grams and then plug the values into the formula to find the heat energy required.

How much heat is necessary to vaporize 500 grams of ice at its freezing point?

The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.
