Using the formula Q=mcΔT, the amount of heat energy required is (30g)(4.18J g-1 K-1)(12K) = 1504.8J = 360 calories.

How many calories are required at 0 degree celsius to melt an ice cube with a mass of 25grams?
For water, the heat of fusion is 80 cal/g. So in other words, this is how many calories are needed to melt 1 gram of water that is frozen. Conversely, when you freeze 1 gram of water, you remove 80 calories of heat from it.... So, you multiply the calories needed to unfreeze a gram of water by the number of grams you have. In this case, 80 * 25 = 2000 Calories
How many calories are needed to warm 25g of water from 65C to 92C?
The answer is 675 calories.
How many calories are needed to raise the temp of 8.1 g of water 20 degrees Celsius?
there are no calories in water you idiot
How many calories of heat are required to raise the temperature of 650g of water from 13.0 C to 20.0 C?
ΔH = cmΔT The change in heat = change in temperature (degrees C) . volume of the liquid (l) . heat capacity of the liquid ΔH = 4.18 . 0.65 . 7 ΔH = 19kJ of heat 1 Calorie = 4.184 kJ so 4.55 Calories are needed to heat 650g of water from 13°C to 20°C but as some heat will be lost to the environment and there will be some incomplete combustion so you will need to burn more to see that actual change in temperature.
How many calories of heat energy are required to melt 10 grams of ice at 0 degrees celciaus?
103 calories. The heat of fusion of water is 80 cal/g and it takes one calorie to change the temperature of 1 g of water by 1 degree. 80+23=103 calories

How many calories are needed to change 1 gram of 100 degrees Celsius boiling water to 100 degrees Celsius steam?
This is the latent heat of vaporisation of water, which at standard pressure, is 539 calories (per gram).
How many calories are needed to warm 25g of water from 65C to 92C?
The answer is 675 calories.
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.
How many calories does it take to heat 1 liter of water 1 degree?
It takes 1000 calories to heat 1 litre of water 1 degree C.
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 calories are needed to raise the temp of 8.1 g of water 20 degrees Celsius?
there are no calories in water you idiot
How many calories are needed to vaporize 1 gram of boiling water at 100 degrees?
540 calories are needed to turn one gram of water at 100 degrees celsius to steam.
How many calories does it take to heat a 100.0 g sample of water from 24.5 degrees to 38.2 degrees?
1370 calories
How many calories of heat is available when a hot water bottle containing 750g of water at 65 degrees cools to body temperature?
there are 3000 calories in a water bottle so be careful!
The specific heat of gold is 0.031 caloriesgram and degC. If 10.0 grams of gold were heated and the temperature of the sample changed by 20.0 and degC how many calories of heat energy were absorbed by?
The needed heat is:Q = 10 x 20 x 0,031 = 6,2 calories
