What amount of heat energy is required to raise the temperature of 45 pounds of lead from 62 degrees to 100 degreesF?
Specific heat of lead = 0.160 J/gC
45 pounds (454 grams/ 1 pound)
= 20430 grams
Use.
q(Joules) = mass * specific heat * change in temp.
q = (20430 grams)(0.160 J/gC)(100 C - 62 C)
= 1.2 X 10^5 Joules

1.2 X 10^5 Joules (1 calorie/4.184 Joules)
= 29688 calories

What is the measure of the amount of heat an object has?
The measure of the amount of heat an object has is its temperature, typically expressed in degrees Celsius or Fahrenheit. Temperature is a reflection of the average kinetic energy of the particles within the object.
How many BTU are generated to get water to 212 degrees?
This question is a little confusing in that BTUs are not generated in raising the temperature of anything; the input of heat is required. And if the questioner meant required instead of generated, then the question is still unanswerable as the amount of water must be specified, AND the starting temperature must be specified.
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.
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 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.
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!
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.
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.
What is the measure of the amount of heat an object has?
The measure of the amount of heat an object has is its temperature, typically expressed in degrees Celsius or Fahrenheit. Temperature is a reflection of the average kinetic energy of the particles within the object.
What is the BTU required to raise the temperature of 10 pounds of water from 50 degrees to 70 degrees?
200 BTU. I'm assuming your temperatures are in Fahrenheit, since all of your other measurements are in the Imperial system. A BTU is defined as the amount of energy required to raise the temperature of 1 pound water by 1 degree F, so the temperature is raised by 20 degrees, and 10 pounds of water: 20 x 10 = 200
How many BTU are generated to get water to 212 degrees?
This question is a little confusing in that BTUs are not generated in raising the temperature of anything; the input of heat is required. And if the questioner meant required instead of generated, then the question is still unanswerable as the amount of water must be specified, AND the starting temperature must be specified.
What are the 3 Measurements of Heat?
The three measurements of heat are temperature, specific heat capacity, and heat capacity. Temperature measures the average kinetic energy of particles in a substance, while specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Heat capacity is the total amount of heat required to raise the temperature of a substance by one degree Celsius.
How many kilowatts are required to raise the temperature of 1000 liters of water by 10 degrees centigrade?

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.
