The specific heat capacity of lead is 0.128 J/g°C. To raise the temperature of 40 g of lead by 1°C, it requires 40 g * 0.128 J/g°C = 5.12 J of energy.
How much heat it takes to raise the temperature
The specific heat capacity of water is 4.18 J/g°C. Therefore, it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
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.
specific heat capacity
To calculate the heat required to raise the temperature of an object, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of the object, c is the specific heat capacity of the material (silver in this case), and ΔT is the change in temperature. Given that the mass (m) is 0.10 kg, the specific heat capacity of silver is approximately 235 J/kg*C, and the change in temperature (ΔT) is 25°C, you can plug these values into the formula to find the heat energy required.

The amount of heat required to raise the temperature of a room depends on the room's size, insulation, current temperature, and the desired temperature. It can be calculated using the specific heat capacity of air, room volume, and the temperature difference.

To calculate the energy required to raise the temperature of a substance, we use the formula: Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. The specific heat capacity of lead is 0.128 J/g°C. Converting the mass to grams (1 kg = 1000 g), we have m = 3000 g. Plugging in the values, we get Q = 3000g * 0.128 J/g°C * (20°C - 15°C) = 1920 Joules. Therefore, 1920 Joules of energy is required to raise the temperature of 3 kg of lead from 15 to 20 degrees Celsius.
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
It doesn't work that way. There is not a certain number of btus to raise air temperature. You would have to know how much air. A BTU is the British Thermal Unit. That is the amount of energy required to raise the temperature of one pound of water one degree F.
Energy required to raise 1 gramme of water by 1 degree C = 1 calorie also, 1 calorie = 4.186 Joules
