How much energy is needed to raise the temperature of 2.0 g of water 5.0 degrees C?
The needed energy is 10 calories.
How much energy is needed to raise the temperature 2.0 g of water 5 at degrees Celsius?
42 J
What provides the energy needed for water to change it states when it evaporates?
The temperature is the most important factor.
What has the more heat energy at 100 degrees Celsius water or steam?
steam. It has to go through a phase change, which takes additional energy to get there.
Why considerable heat energy is needed to convert 1g of water into 1g of steam at 100c without any change in temperature taking place?
There is heat needed to transform the configuration of liquid water to gaseous state. This is change of state energy changes the configuration without changing the temperature.
What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
How much energy is needed to raise the temperature of 2.0 g of water 5.0 degrees C?
The needed energy is 10 calories.
What is the unit of measurement of energy needed to heat one kilogram of water by 2 degrees F?
It is a calorie
What is needed for water to change from a solid to a liquid?
A room temperature ubove 0 degrees centigrade.
What is needed to change water from a solid to a liquid?
A room temperature ubove 0 degrees centigrade.
How much energy is needed to raise the temperature 2.0 g of water 5 at degrees Celsius?
42 J
How many joules are needed to change the temperature of 100 g of water from 20 degrees Celsius to 40 degrees celsius?
8.200 J
How much energy is needed to reduce water temperature from 15 degrees to 14 degrees?
1 calorie increases 1 gram of water by 1 degree celsius. 4.18 Joules are needed to increase the temperature of 1 gram of water by 1 degree celsius. To reduce the 1 gram of water 1 degree celsius it would have to give off 1 calorie of energy. To calculate the energy multiply the mass in grams of water by 4.18 and by the change in temperature. The energy = 4.18 x m x change in T. The answer is in Joules. If you are using calorie as the unit of energy, replace 4.18 J by 1 C. Note that food is measured in kilocalories (Calories) not metric calories.
What is an amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy?
The amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy is 42,2g H2O.
What provides the energy needed for water to change it states when it evaporates?
The temperature is the most important factor.
What energy is needed for water to turn into water vapour?
As soon as the temperature drops below the dew point, water will condense from water vapor.
What has the more heat energy at 100 degrees Celsius water or steam?
steam. It has to go through a phase change, which takes additional energy to get there.
