To determine how much energy is needed to heat 0.7 kg (700 g) of sand from 10 degrees to 70 degrees C, one first need to know the specific heat of sand. It turns out to be about 0.83 J/g/deg.
Thus, to calculate heat needed, use the equation q = mC∆T where m=mass; C=0.83 J/g/deg and ∆T = change in temperature = 60 degrees (70-10). Then q = (700g)(0.83 J/g/deg)(60 deg) = 34,860 Joules. If you want to convert this to calories, it would be 34,860 J x 1 calorie/4.184 Joules = 8,331 calories.

What is the thermal energy needed to completely melt 9.60 mol of ice at 0.0 degrees celsius?
Anything hotter than 0 degrees that radiates heat.
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.
What has the more heat energy at 100 degrees Celsius water or steam?
steam. It has to go through a phase change, which takes additional energy to get there.

What property of a material tells you how much energy it can store?
Specific heat capacity tells you how much stuff energy can store. specific heat capacity is the amount of energy needed to raise the temperature of 1kg of a substance by 1 degrees celsius. water has a specific heat capacity of 4200 J/kg degrees celsius.

How many calories are needed to heat up 5 grams of water by 3 degrees Celsius?
(5)(3)= 15 calories. 1 calorie is the energy (heat) to raise 1 gram of water by 1 degree celsius, so 5 grams of water (3 degrees Celsius) = 15.
What is the thermal energy needed to completely melt 9.60 mol of ice at 0.0 degrees celsius?
Anything hotter than 0 degrees that radiates heat.
How does it measure heat energy?
Heat energy is measured as temperature in Kelvins [K] (also degrees Celsius [°C] and degrees Fahrenheit [°F]) and tells us the average kinetic energy of the molecules.
How many joules of energy are needed to heat steam from 100 celsius to 114 celsius?
Approx 2940 Joules.
How much heat energy would be required to bring a 15 kg block of ice from -20 degrees Celsius to steam at 120 degrees Celsius?
46389000 j
Is a calorie a measure of mechanical energy?
No, it measures the ammount of heat output that would heat a millilitre of water 1 degree Celsius. So if you were to burn 1000 calories of energy, it would heat one millilitre 1000 degrees Celsius or it would heat 1 litre 1 degree Celsius.
What is an amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy?
The amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy is 42,2g H2O.
