How much energy is required to heat 955 g of water from 20 degrees C to 100 degrees C?
4.1858 joules of energy will raise the temperature of 1 g of water by 1oC. Thus, 4.1858 * 955 * 80 = 319795.12 joules of energy is required to raise the temperature of 955 g of water by 1oC.
How many joules are required to boil 21.1 g of water at 100 C?
The needed heat is 47,65 Joules.
What is the amount of heat required in joules to heat 82g of water from 24C to 66C?
Using the formula Q=mcΔT, the amount of heat energy required is (82g)(4.18J g-1 K-1)(42K) = 14400J.
Is water evaporating an exothermic process?
The evaporation of water is endothermic. In order for the hydrogen bonds to be broken in water (which is required for water to evaporate), an input of energy is needed. Conversely, the condensation of water vapor is exothermic.
A sample of H20 with a mass of 46.0 grams has a temperature of 100 c How many joules of energy are necessary to boil the water?
The heat of vaporization is about 2258 joules/gram46 x 2258 = 103,868 J ~ 103.9 kJ(Using the rounded value 2260 joules per gram, about 104 kJ)it is already at boiling point so in theory zero energy is required.I think the question is asking what energy is required to free the water from its liquid state to the vapour state.At 101325Pa, (1 atmosphere in old money), the latent heat of evaporation of water is 2256.7 J/g.So 2256.7 * 46 = 103808 Joules
How much energy is required to heat 955 g of water from 20 degrees C to 100 degrees C?
4.1858 joules of energy will raise the temperature of 1 g of water by 1oC. Thus, 4.1858 * 955 * 80 = 319795.12 joules of energy is required to raise the temperature of 955 g of water by 1oC.
During which process does water gain the most heat energy?
Evaporation because it requires 2,260 Joules to gain heat energy. Condensation, freezing, and melting require less Joules than evaporation.
How many joules of energy are required to raise the temperature of 74g of water from 20 degrees to 70 degrees celsius?
15480.80
What is the difference between btus and joules?
1 BTU is the energy required to heat 1 pound of water by 1 degree F. 1 Joule is defined mechanically, but in thermal terms it is 1/4.2 of a calorie (4.2 Joules/calorie), and 1 calorie is the energy required to heat 1 gram of water by 1 degree C. In fact 1 BTU = 1055 Joules.
How much energy is required to raise the temperature of 1 g of water 1 degree Celsius?
Energy required to raise 1 gramme of water by 1 degree C = 1 calorie also, 1 calorie = 4.186 Joules
How many joules of energy are required to raise the temperature of 150.0g of water from 274K to 318K?
4.184 J/g/K = 4.184 x 150 x (318-274) = 27614 Joules
When or where is ATP required in the process of water transport?
Generally it isn't, diffusion is a process that requires no energy.
How much energy does it take to heat 1 kg of water from 33 deg F to 34 deg F?
The energy required to raise the temperature of water depends on the atmospheric pressure as well as the starting temperature. At a pressure of one atmosphere, the amount of energy required to raise the temperature of water from 0 deg C to 100 deg C (32 to 212 deg F) is 4.19 joules per gram. At 4 deg C, (39.2 deg F) it is approx 4.204 joules per gram per deg C. That is 4.204/1.8 = 2.33555... recurring joules per gram per deg F and so, for a kilogram, the energy required is 2335.55... joules.
Suppose you want to heat 40g of water by 20c how many joules of heat are required?
334.8 Joules
When gaseous water condenses back into liquid water to make clouds is heat energy required by the process or is it released?
Energy is released.
Which would require a greater amount of heat water or iron?
To raise the temperature of both an equal amount, water would require more energy. In terms of the energy required to raise the temperature: iron = 0.45 joules / gram . kelvin water = 4.2 joules / gram . kelvin This is known as the specific heat capacity of a material
How many joules are required to boil 21.1 g of water at 100 C?
The needed heat is 47,65 Joules.
