How many kilowatts are required to raise the temperature of 1000 liters of water by 10 degrees centigrade?
Kilowatts is a unit of energy rate, while the temperature required to raise a specific volume of water by a specific amount of degrees is a unit of energy, not energy rate. The question cannot, therefore, be answered as stated. Please restate the question.
How do you calculate the total heat required in kcal to take 70 grams of ice at -29.0 Celsius and convert it to steam at 106 Celsius?
heat energy required to raise the temperature of ice by 29 celsius =specific heat capacity of ice * temperature change *mass of ice + to change 1kg of ice at 0 celsius to water at 0 celsius =specific latent of fusion of ice*mass of water + heat energy required to raise the temperature of water by 106 celsius =specific heat capacity of water * temperature change *mass of ice + to change 1kg of water at 106 celsius to steam at 106 celsius =specific latent of fusion of ice*mass of steam
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
What does the amount of energy needed to heat water depend on?
The equation Q=mcΔ t calculates the amount of energy for a body of mass to raise a unit temperature per unit mass. The specific heat capacity of water is 4.19 J/g°C which means that it takes 4.19 J to raise 1 g of water to 1°. The specific heat capacity also depends on what the surrounding temperature is. 4.19 J/g°C is the specific heat capacity at room temperature. Since temperature is the measurement of the average kinetic energy of the particles, the motion of particles in water affects the specific heat capacity which ultimately affects how much energy is needed to heat up water.
How is specific heat related to thermal energy?
specific heat is the amount of thermal energy needed to raise the temperature of an object. for example, the water on the beach and the sand on the shore are absorbing the same amount of thermal energy from the sun but the water (which has high specific heat) is cold, and the sand (with low specific heat) is very hot.
Is it harder to raise the temperature of a rock than it is to raise the temperature of water?
It is harder to raise the temperature of water than it is to raise the temperature of a rock. It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C, whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.
Does it take more energy as heat to raise the temperature of water by one degree than to raise the temperature of steam by the same amount?
Yes. The specific heat capacity of liquid water is 4.184 J/g•oC, and the specific heat capacity of steam is 2.010 J/g•oC.
What does it mean to have a specific heat greater than water?
It means that it takes more energy to raise the object's temperature by 1 degree than it does to increase the temperature of water by 1 degree..
Water has a temp of 4.184 and copper has a temp of 0.387. Does it takes more heat to raise the temp of the copper molecule?
These are not temperature numbers but specific heat numbers. They mean that it takes 4.184 Joules and 0.387 Joules respectively to raise water and copper of one gram by one degree celsius. So, as you can see, it takes a lot more heat to raise the temperature of water than it does of copper. Water has a very high specific heat.

Which is affected more when you increase the temperature?
Water is something that will be affected if you raise the temperature. When cooking, you may need to raise the temperature of water to a boil, in order to cook food.
What does water help to regulate?
Water's high specific heat capacity helps to maintain body temperature. High specific heat capacity indicates a need for more energy to raise or lower the temperature of water. Sweat is another way that water helps maintain temperature. When sweat evaporates it draws in energy from the surroundings (the air and the body surfaces it is in contact with), effectively lowering the temperature.
What is the specific heat of liquid water?
This is the necessary energy to raise the temperature of 1 gram with 1 kelvin.
When liquid water is heated most of the energy that the water initially absorbs is used to do?
It is used to raise the temperature of the water.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What is to raise the temperature of 1 gram of water 1 degree Clntigrade?
Depends on how high you want to raise the gram of water ;).
