How many kilocalories does it take to heat water from 65 oF to 105 oF?
To heat 1 gram of water by 1 degree Celsius, it takes 1 calorie. Therefore, to heat water from 65 oF to 105 oF, you would need 40 calories per gram of water. If you are working in kilocalories, this would be equivalent to 0.04 kilocalories.
How many kilocalories of heat does the operation of a 1200-W hair dryer produce each second?
The heat produced by a 1200-W hair dryer can be converted to kilocalories by multiplying the power in watts by the conversion factor of 0.001 kcal/s per watt. Therefore, 1200 W hair dryer would produce 1.2 kilocalories of heat each second.
How many kilocalories are needes to heat form 62F to 105F?
To calculate the number of kilocalories required to heat something up, you need to know the specific heat capacity of the substance. The specific heat capacity of water is 1 calorie/gram°C. The formula to calculate the heat energy required is Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.
In what units is heat flow measured?
Heat flow is typically measured in units of watts (W) or joules per second (J/s).
A college student produces about 100 kilocalories of heat per hour on the average what is the rate of energy production in watts?
To convert kilocalories per hour to watts, divide by 860: 100 kilocalories per hour / 860 = 0.1163 watts. So, the college student's rate of energy production is approximately 0.1163 watts.
How many kilocalories of heat does an expenditure of 551 kJ produce?
Relative to liquids and gasses, they have the least amount of energy. In terms of the actual particles themselves, the amount of energy they possess depends on their structure and composition along with the temperature.
How many calories of heat does an expenditure of 250 kJ produce?
An expenditure of 150 kJ produces approximately 62.5 calories of heat.
How many kilo calories of heat does an expenditure of 250 kj produce?
59.711 kilo calories of heat are produced from 250 kilojoules. 5 kilojoules are equivalent to 1 kilo calorie of heat.

What does kilocalories mean?
Kilo means 1,000, so kilocalories means a thousand calories.

What is affect of cold climate on human metabolism?
Cold climate can increase metabolism as the body works harder to maintain its core temperature. This can lead to higher calorie expenditure to generate heat. Additionally, cold can stimulate the production of brown adipose tissue, which burns calories to produce heat.
Do heaters produce heat or use heat?
Heaters use electricity to produce heat by resistance.
