Why does Hot water extinguishes fire more effectively than cold water?
Hot Water extinguishes more effectively than cold water as it has a higher specific heat capacity than cold water.
How can the specific heat of water be used to determine the specific heat of an object?
If you know the temperature and mass of an object, and the temperature, mass, and specific heat of the water, if you dunk the object in the water, and measure the temperature of the water and the object (once the object and water have the same temperature), using reasoning skills and/or equations you can figure out the specific heat of the object. Historically the specific heat was related to SH of water . Water being 1 That now is seen as archaic. The specific heat (of a substance) is the amount of heat per unit mass required to raise the temperature by one degree Celsius. This does not apply if a phase change is encountered. Every substance has to be measured separately .
What has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
Which cools your body temperature down more cold water or hot coffee?
Specific heat is the amount of heat energy required to raise the temperature of a given mass of matter by a certain amount. Water requires 1 calorie of heat to raise the temperature of 1 gram by 1 degree centigrade. It's specific heat is 1. Ice has a specific heat of about 0.5, meaning that it would only require about 1/2 calorie to raise the temp of 1 gram of ice by 1 degree C. Coffee has a higher specific heat, regardless of whether it is hot or cold.
How are specific heat of water and ice the same?
That is how specific heat is defined. When you measure something you have to measure it relative to some point of reference. In specific heat it was agreed upon that water was to be the standard and its specific heat would be one. Therefore everything else is measured relative to water.
Does hot water have a lower specific heat than cold water?
No
How much heat energy is tranferred to hot water?
The specific heat of water is 4,186 J/g.K.
Why Water is used in hot water bags why?
Due To high specific heat
Why water is used in hot bags?
Due To high specific heat
Does a high or low specific heat mean the substance heats up so fast?
low specific heat is like sand and high specific heat is like water at the beach it may be hot outside the water is still cold but the sand is hot as ever.
How is specific heat related to thermal heat?
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.
Why does the bath stay hot for so long?
water has a high specific heat, meaning it stores a lot of heat energy.
Why does Hot water extinguishes fire more effectively than cold water?
Hot Water extinguishes more effectively than cold water as it has a higher specific heat capacity than cold water.

If the specific heat of aluminum is 0.902 and the specific heat of copper is 0.268 what makes copper a better choice to use for hot water lines in your house?
This means that copper will not absorb the heat from the water as much as the aluminum. Aluminum will "steal" more heat from the water- which you do not want. You need the heat to stay with the water until it serves its purpose.
Why does land become hot faster than a body of water?
Water heats slower because it has a higher specific heat capacity.
