Heat of vaporization of water is 2.26 x 106 joules per kg.
Therefore 1 gram of water will need 2.26 x 103 joules.
It is not zero so the question is based on a false assumption.
No. Those are units of temperature. Heat is measured in units of energy, such as the joule.
One degree Fahrenheit is equal to 0.5556 degrees Celsius. To convert this temperature change to energy in joules, you would need to know the specific heat capacity of the substance in question. The formula to calculate the energy change in joules is Q = mcΔT, where Q is the energy change, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change in degrees Celsius.
Three temperature scales are in common use in science and industry. Two of those scales are SI metric: The degree Celsius (°C) scale was devised by dividing the range of temperature between the freezing and boiling temperatures of pure water at standard atmospheric conditions (sea level pressure) into 100 equal parts. Temperatures on this scale were at one time known as degrees centigrade, however it is no longer correct to use that terminology. [The official name was changed from "centigrade degree" to "Celsius degree" by the 9th General Conference on Weights and Measures (CGPM) in 1948.] The kelvin (K)temperature scale is an extension of the degree Celsius scale down to absolute zero, a hypothetical temperature characterized by a complete absence of heat energy. Temperatures on this scale are called kelvins, NOT degrees kelvin, kelvin is not capitalized, and the symbol (capital K) stands alone with no degree symbol. [The official name was changed to "kelvin" and symbol "K" by the 13th General Conference on Weights and Measures (CGPM) in 1967.] The degree Fahrenheit (°F)non-metric temperature scale was devised and evolved over time so that the freezing and boiling temperatures of water are whole numbers, but not round numbers as in the Celsius temperature scale.
5 degrees warmer than -1 degrees = 4
The final temperature of the mixture will be between 5 and 20 degrees Celsius, closer to 5 degrees since a larger mass of water is at that temperature. To find the exact final temperature, you can use the principle of conservation of energy (Q lost = Q gained).
You can't convert units of temperature to units of energy.
Steam has enough kinetic energy to leave the liquid water that is boiling, so it's greater amount of energy results in more severe burns than boiling water, which has a lower amount of energy.
It is not zero so the question is based on a false assumption.
No. Those are units of temperature. Heat is measured in units of energy, such as the joule.
The specific heat of water is 4.179 Joules per gram per degree Centigrade. The density of water is 1 gram per cubic centimeter, so one liter is 1000 grams. This means it takes 4179 Joules to raise one liter one degree Centigrade.
1 centigrade heat unit (International Table) = 0.52752793 watthour
Yes, your body uses a thermal energy known as caloric energy called "calories." A calorie is the amount of thermal energy required to heat one gram of water by one degree centigrade.
A calorie is the amount of heat required to warm 1 gram of water one degree Centigrade. A Calorie spelt with a big "C" is a kilocalorie and is used in evaluating food energy. It is the heat required to raise 1 kilogram of water one Centigrade degree. On an energy basis a calorie is 41 840 000 ergs.
The oil fired boiler is typically set at 65 degrees centigrade to ensure the water in the heating system reaches a sufficient temperature to effectively heat the property without wasting energy or causing overheating. This temperature setting helps achieve a balance between comfort and efficiency in heating the space.
Liquid boils when it reaches 100 degrees Fahrenheit.Additional answerHey, come on! Not all liquids boil at 100 degrees Fahrenheit. Water boils at 100 degrees centigrade, for example. Each liquid has a different boiling point.
Less than 1% of the world's commercial energy is supplied by solar energy.
