A substance that has a specific heat that is higher than liquid water and explain what it means?
that means more energy is needed to raise the temperature of 1kg of liquid from 1 Celsius than water.
Why is a great deal of heat needed to raise the temperature of water by a given amount?
because it has a great heat capacity
Why has a candle got a higher temperature but less heat energy than a bowl of warm washing up water?
Simply it's because Heat and Temperature are not interchangeable. They're not the same thing. Heat is a form of energy. Temperature is not. When heat encounters a substance, it can change the state of the substance or raise it's temperature. Temperature is only a measurement that relates to the molecules kinetic energy. But it says nothing about potential energy. Consider for a moment how much TOTAL potential heat energy is in even a bowl of warm water. You would need a lot of energy to raise a cold bowl of water to that same warm temperature? Could the candle do it? Possibly, but over a long period. That flame might be hot, but it doesn't possess the same energy? Btw: Water has a considerably high Specific Heat, which is the amount of heat (energy) required to raise it's temperature by 1 degree for 1 gram
How much heat is required to raise the temperature of 350 grams of water from 22 degrees C?
1 calorie is needed to raise 1 g of water 1 °C. 350 * 22 = 7700 calories ■
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.

How many calories of heat needed to raise temperature of 8.1 g of water 20C?
1 calorie is defined as the amount of energy needed to raise the temperature of 1 gram of water by 1C, so... It takes 8.1 calories to raise your 8.1 grams by 1C, but you need to raise it 20C. 8.1*20=162. 162 calories is the answer you are looking for.
How much heat is in fresh water?
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
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.
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 ;).
Define Joule calorie and Kcal?
A calorie is the amount of energy that needed to raise the temperature of one gram of water one degree Celsius. The Joule is the SI unit for energy.
What is the amount of energy needed to raise the temperature of 1 gram of water 1 degree celsius?
