How much energy is needed to raise the temperature of air by 1 degree Celsius?
.02 btu
Why is a great deal of heat needed to raise the temperature of water by a given amount?
because it has a great heat capacity
What could affect the temperature at which water boils?
The pressure of the atmosphere around the water determines the temperature at which it boils. Also, the presence of dissolved particles in the water will raise the boiling temperature.Dissolved solids (salt, sugar or anything else in there, This will raise the temperature). Pressure lower pressure means less temperature needed to boild the warer. (altitue on earth will do this cause higher altitudes means lower pressureDissolved solids (salt, sugar or anything else in there, This will raise the temperature).

How much heat is required to raise the temperature of 350 grams of water from 22 degrees C?
1 calorie is needed to raise 1 g of water 1 °C. 350 * 22 = 7700 calories ■
What chemical can be used to make iron melt?
No chemicals needed: just raise the temperature. Melting is never a chemical change, but purely physical!
The number of kilojoules needed to raise the temperature of 32.0 g of water from 12.0 degree centigrade to 54.0 degree centigrade is?
q(Joules) = mass * specific heat * change in temperature q = 32.0 grams H2O * 4.180 J/gC *(54.0 C - 12.0 C) = 5617.92 Joules this is, of course 5.62 kilojoules
How much heat is in fresh water?
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.
What do you use to raise the temperature on a fish tank?
A heater can raise the temperature of a fish tank if needed
What are the factors that determine the amount of energy needed to raise the temperature?
Mass, heat capacity, the desired raise in temperature.
What is the total number of calories of heat needed to raise to raise the temperature of the liquid water from 20 degrees Celsius to 30 degrees Celsius?
The number of calories required will depend on the mass of water which is to be heated.
how many kilojoules of heat are required to raise 10.00 g of jce at 0°C to steam at 100°C?
initially at-10.0 c, the steam at 115 c. in kilojoules,is required to ralse the temperature of 2.50 kg HG from 20.0 to 6.0 c
A calorie is the amount of energy needed to?
raise the temperature of the body by 1 Celsius
How many calories of heat needed to raise temperature of 8.1 g of water 20C?
1 calorie is defined as the amount of energy needed to raise the temperature of 1 gram of water by 1C, so... It takes 8.1 calories to raise your 8.1 grams by 1C, but you need to raise it 20C. 8.1*20=162. 162 calories is the answer you are looking for.

How many kilojoules of energy are necessary to raise the temperature of 3 kilograms of cast iron from 30 degrees celsius to 120 degrees celsius?
I will use this formula. Some conversion will be required. ( I only know specific heat iron in J/gC ) q(Joules) = mass * specific heat * change in temperature Celsius 3 kilograms cast iron = 3000 grams q = (3000 g)(0.46 J/gC)(120 C - 30 C) = 124200 Joules (1 kilojoule/1000 joules) = 124.2 kilojoules of energy needed ===========================
