What effect does the initial temperature of the water have on change in temperature of the water after the hot metal is added?
When hot metal is added into the water then the metal looses its energy into the water and this heat is gained by the water, so the temperature gets increases when hot metal added into it i.e final temperature is greater than initial temperature of water.
Why is water an excellent material to use in a calorimeter?
Water is an excellent material to use in a calorimeter because it has a very high specific heat, making it very hard for water to raise its temperature even by 1 degree celsius, but as hard as it was to raise the temperature of the water, it is equally as hard to lower the temperature of the water-making it able to effectively retain heat and allowing the other material inside of the calorimeter to absorb that heat.
When 418 joules of heat energy are added to 10 grams of water at 20C the final temperature of the water will be?
21
Which salt will result in a temperature increase when added to water?
The salt that will result in a temperature increase when added to water is calcium chloride (CaCl2). This is because it is an exothermic salt, meaning it releases heat when dissolved in water.
Do covalent bonds give water low heat capacity?
Water has a relatively high heat capacity, not a low heat capacity. Heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. Water has a high heat capacity because it requires a lot of energy to raise its temperature. This property of water is due to the strong hydrogen bonds between its molecules, which require a lot of energy to break. As a result, water can absorb or release a large amount of heat without undergoing a significant change in temperature, making it an excellent heat sink. The specific heat capacity of water is the amount of energy required to raise the temperature of a substance by 1 degree Celsius (or 1 Kelvin). Water has a high specific heat capacity because it requires a lot of energy to raise its temperature. This property of water makes it an important factor in the regulation of temperature in living organisms and in the Earth's climate. It is also why water is often used as a coolant in various types of cooling systems, such as in car radiators and air conditioners.
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.
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.
What effect does the initial temperature of the water have on change in temperature of the water after the hot metal is added?
When hot metal is added into the water then the metal looses its energy into the water and this heat is gained by the water, so the temperature gets increases when hot metal added into it i.e final temperature is greater than initial temperature of 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
Does metal with high heat capacity raise temperature of water more than a metal with low heat capacity?
yes
How can you change ice into water?
The best way is to remove heat by cooling.
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.
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 is the specific heat of a substance?
The amount of heat a substance can hold.
Why is water an excellent material to use in a calorimeter?

Taking heat out of the air will do what to the temperature?
Removing heat from the air will lower its temperature.
Which common substance requires the most heat to raise the temperature of a gram by 1 degree Celsius?
water
