Why do heat gives heat than cold temperature?

Beause heat is transfered by high temp to low temp.If a system heats up so that its temperature is greater than atmospheric temperature the systan has high temp than atmospheric temp as heat transfer from high temp to low temp heat radiates from the system.


Does the temp. of water change more slowly than the temp of land?

Yes, water has a very high "heat capacity".


If water temp changes 15 degrees C how much heat was gained by the water?

the information given is incomplete to tell the heat gained by water it also requires the amount of water taken and whether the temp has decreases or increased


When i warmed up the car the temp gauge read warm but no heat was coming out and it started to smoke?

Check you've got water in the cooling system.


How many degrees should your water be in a car?

water/coolant temperature is controlled and maintained by the thermostat, most common temp. is 192 F. This temp allows both most efficient engine operation and adequate cabin heat.


What should supply air temp be for heat pump heating?

With heat pumps supply air temp will vary with outdoor temp. The colder it gets outside the less efficient the heat pump will be (colder supply air).

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.


What quantities do you need to know in order to determine the amount of heat released by the lead sinker in cooling to the final temperature?

mass of water, initial temp of the water, final temp of water after the hot sinker is put into the water, the temp of the hot sinker (if it is heated in separate boiling water, the temperature of the water) and the specific heat of water ( 1 cal/g degree C)


Is a water temp sensor the same thing as a coolant temp sensor?

Yes, but it is not recommended to run straight water in the cooling system.
