What amount of heat energy in Btus is required to raise the temperature of 45 pounds of lead from 62 degrees F to 100 degrees F?
You like the old units! I'll work in SI then give you the answer in BTU. Specific heat capacity of lead = 0.127 KJ.Kg-1.C-1 (kilojoules per kilogram per deg C). 45 lb = 20.41 kg.
100 - 62 = 38 deg F = 21.11 degC.
So heat energy = 0.127 x 20.41 x 21.11 = 54.72 KJ. 1 KJ = 0.9478 BTU

What is the amount of energy in plasma?
It can vary; a plasma can have a temperature of a few thousand degrees, or millions, or even billions of degrees - in each case, the amount of energy will be different. Of course, the amount of energy will also depend on the amount of plasma we are talking about.
How many kilowatts are required to raise the temperature of 1000 liters of water by 10 degrees centigrade?
Kilowatts is a unit of energy rate, while the temperature required to raise a specific volume of water by a specific amount of degrees is a unit of energy, not energy rate. The question cannot, therefore, be answered as stated. Please restate the question.
How much energy would you use to raise temperature of kg of water by 2 degrees Celsius?
The amount of energy required to raise the temperature of 1 kg of water by 1 degree Celsius is approximately 4,186 Joules. Therefore, to raise the temperature by 2 degrees Celsius, you would need about 8,372 Joules of energy.
How much heat energy is required to raise the temperature of 0.362 kg of copper from 23.0 degrees Celsius to 60.0 degrees Celsius?
The amount of heat energy required can be calculated using the formula: Q = mcΔT. Given m = 0.362 kg, c = 390 J/kg°C for copper, and ΔT = (60.0 - 23.0) = 37.0 °C, plug these values into the formula to find the heat energy required to raise the temperature of the copper.
How much heat energy is required to raise the temperature of 5 kilograms of cool from 20 degrees celto 220 degrees cel?
The amount of heat energy required to raise the temperature of a substance 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. First, calculate the change in temperature (220°C - 20°C = 200°C), then use the specific heat capacity of the substance to find the heat energy.
What term describes the amount of thermal energy that is required to raise the temperature of a substance by 1.0 degrees Celsius?
Specific heat capacity is the term that describes the amount of thermal energy required to raise the temperature of a substance by 1.0 degree Celsius.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What is the amount of energy in plasma?
It can vary; a plasma can have a temperature of a few thousand degrees, or millions, or even billions of degrees - in each case, the amount of energy will be different. Of course, the amount of energy will also depend on the amount of plasma we are talking about.
True or false a calorie is the amount of heat energy required to raise the temperature of 1 g of water 2 degrees C?
True. A calorie is defined as the amount of heat energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.
Is temperature measured in calories?
No, temperature is not measured in calories. Temperature is typically measured in degrees Celsius (°C) or degrees Fahrenheit (°F), while calories are units of energy related to the amount of heat required to raise the temperature of one gram of water by one degree Celsius.
Is degrees related to thermal energy?
The amount of thermal energy a substance has is proportional to its temperature

Is a green heating system unable to go beyond 68 degrees?
If you are asking why a green heating system will not go above 68 degrees Fahrenheit then one reason is to save energy. The higher the temperature the more energy required to get to that temperature and the more energy required to keep that temperature.
