The work done is transformed into potential energy (in the object lifted) so
W = m x g x dz where
W = Work
m = mass
g = acceleration due to gravity
dz = change in height
=> W = 1kg x 1m x 9.81m/s/s
=> W = 9.81J
1J = 0.239 calories
=> It takes 2.345 calories to lift 1kg by 1m
NOTE
These are "real" calories. The calories usually talked about in relation to dieting etc are kilo-calories so to equate this value to the calories in a chocolate bar, divide by 1000

How many calories of heat would it take to raise the temperature of 256 grams of water from 20 degrees to 99 degrees?
A calorie is the amount of heat you need to raise the temperature of one gram of water by one degree Celsius. Assuming you are raising the temperature of the water from twenty degrees Celsius to ninety-nine degrees Celsius, it would take 20,000 calories. To calculate this, subtract 20 from 99. This is the amount of degrees you need to raise the temperature of the water by. Then multiply that number by 256, the amount of water in grams. You should get 20,244 calories. In significant digits, your answer should be 20,000 calories.

How long would it take to burn off 4000 calories?
The time it takes to burn off 4,000 calories depends on several factors, including your weight, activity level, and the type of exercise you're doing. On average, a person may burn around 300-600 calories per hour with moderate to vigorous exercise. However, this can vary significantly. Here's a rough estimate of the time it might take to burn 4,000 calories for a person with an average calorie burn rate: Walking: If you're walking at a moderate pace (3-4 mph), you might burn around 250-400 calories per hour. So, it could take approximately 10-16 hours of walking to burn off 4,000 calories. Running: Running at a moderate pace (5-6 mph) can burn around 600-800 calories per hour. It would take about 5-7 hours of running to burn 4,000 calories. Biking: Cycling at a moderate speed (12-14 mph) can also burn around 600-800 calories per hour. It would take approximately 5-7 hours of cycling to burn off 4,000 calories. Swimming: Swimming can be an effective way to burn calories, and you might burn 500-700 calories per hour. So, it would take roughly 6-8 hours of swimming to burn 4,000 calories. High-Intensity Interval Training (HIIT): HIIT workouts can be very effective for calorie burning. Depending on the intensity, you might burn 400-800 calories in an hour. So, it could take 5-10 hours of HIIT to burn 4,000 calories. Please note that these are approximate estimates, and individual calorie burn rates can vary significantly. Your age, gender, fitness level, and other factors can influence how many calories you burn during exercise. It's also important to consider that diet and overall lifestyle play a significant role in managing your calorie balance. If you're trying to lose weight or manage your calorie intake, it's often more practical to focus on your diet in addition to exercise.

About how many calories would it take to boil a gallon of fresh water?
A calorie (kcal) is the amount of energy it takes to raise the temperature of 1 kg water by 1 °C. Water weighs about 1000 kg per cubic meter, which is equivalent to approximately 3.79 kg per gallon. Assuming the water is at room temperature (25 °C), it will take about 284 calories to raise one gallon of water to near boiling (100 °C). In order to actually boil, at least part of the water must be turned into steam. It takes 540 calories per 1 kg to turn water into steam, so it will take some additional energy beyond the 284 to actually bring the water to a boil.
