How many joules of heat are required to heat 65g lead from 22.0 degrees centigrade to 98.5 degrees centigrade?
The specific heat capacity of lead is 0.128 J/g°C. First, calculate the change in temperature: 98.5°C - 22.0°C = 76.5°C. Next, calculate the heat energy using the formula Q = mcΔT where m = 65g, c = 0.128 J/g°C, and ΔT = 76.5°C. Substituting the values gives Q = 65g * 0.128 J/g°C * 76.5°C = 625.2 Joules.

How much joules does it take to heat water to 100 degrees?
To heat 1 gram of water by 1 degree Celsius, it takes 4.18 joules. So, to heat water from, for example, 20 degrees to 100 degrees, you would need to calculate the total mass of water and apply the specific heat capacity to determine the total energy required.
How much heat is required to raise the temperature of 15 kg of water from 22 degree centigrade to 35 degree centigrade?
The specific heat capacity of water is 4.18 J/g°C. 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, we can calculate that the heat required is approximately 20910 Joules or 20.91 kJ.
How many joules does it take to raise temperature from 30 degrees Celsius to 45 degrees Celsius?
To raise the temperature of a substance, you need to calculate the heat energy using the specific heat capacity of the substance. Without knowing the specific heat capacity of the substance in question, it's not possible to determine the exact amount of energy required to raise the temperature from 30 to 45 degrees Celsius.
How much energy is required to raise the temperature of one liter of water 1 degree centigrade?
The specific heat of water is 4.179 Joules per gram per degree Centigrade. The density of water is 1 gram per cubic centimeter, so one liter is 1000 grams. This means it takes 4179 Joules to raise one liter one degree Centigrade.
The specific heat of gold is 0.131 Joules per gram. Celsius How much energy is required to heat 1.3 grams of gold from 25 Celsius to 46 Celsius?
The change in temperature is 21 degrees Celsius. To calculate the energy required, we use the formula: Energy = mass * specific heat * change in temperature. Plugging in the values, Energy = 1.3g * 0.131 J/g°C * 21°C = 35.247 Joules. Therefore, 35.247 Joules of energy is required to heat 1.3 grams of gold from 25°C to 46°C.
How much energy must be supplied to turn 1 gram of water at 100 degrees centigrade to steam at 100 degree centigrade?
