To answer this question, you need to know the heat capacity (C) for silver (Ag). It happens to be 0.240 J/g/deg. Then you can use the formula q = mC∆T where q = heat; m = mass; C = sp.heat cap; ∆T = change in temp. q = (252 g)(0.240 J/g/deg)(63.2 deg) = 3822 Joules

Substance which conduct electricity but not heat?
Most of the metals are good conductors of both electricity and heat. However, silver conducts heat very poorly. Substances made out of silver like silver spoon will not conduct much heat.
How much heat is liberated at constant pressure if 0.904 g of calcium carbonate reacts with 17.1 mL of 0.121 M hydrochloric acid?
-0.0157 kJ
What would cause silver to turn a copper color?
if you apply to much heat to it can cause the copper to pool at the heat source. this happens because of the different melting temperature between the 2 metals. silver usually has about 7.5% copper in it.
How do you tell the difference between silver and metal?
Silver is a metal so I guess you mean iron or steel. • If it is magnetic it is not silver. • Silver conducts heat/cold very well. if you put a solid silver object in hot water it will transmit the heat to your fingers quicker than steel. • You can buy small bottles of acid to test for gold and silver online for less than $10 • If it's big enough you can do an archimedes test by measuring how much water it displaces and finding its density by comparing its volume to weight.
When water is heated it?
When heat is removed from a gas the gas will start a process called Condensation. Condensation is when a gas becomes too cold to maintain it's state and starts to collect itself into a liquid. Some gases need to be much colder than other gases to start to condense.
How much heat is released when 1 kg of molten iron cools?
The answer will depend on its starting temperature and its final temperature.
How much heat is lost when 640 g piece of copper cools from 375 celsius to 26 celsius?
86000j
Why diamond conduct more heat than silver?
Yes, by some accounts as much as five times more heat than silver or copper.

How much rest should be given a patient with heat cramps?
A patient with heat cramps should rest until the body cools down. Heat cramps are an indicator of the body overheating and heat exhaustion could occur.
How much heat is liberated at constant pressure if 0.904 g of calcium carbonate reacts with 17.1 mL of 0.121 M hydrochloric acid?
-0.0157 kJ
How much heat energy is liberated when potassium reacts with water?
When potassium reacts with water it releases 160KJ of heat energy. This answer relates to chemical reaction's. I suggest you research the question just to make sure! I hope this helps...
How will the climate change if we wern't so close to the ocean?
It would get cooler because of the high specific heat of water found in the ocean. Basically the ocean absorbs much heat which cools the area around it.
How much heat is lost when a 4110 gram metal bar whose specific heat is 0.2311 Jg C cools from 100C to 20C?
4110 x 0,2311 x 80 = 75,986 kJ
What happens when gas cools too much?
it will condense and turn into liquids and if that cools too much it will turn to solid
What are some important uses of silver?
Silver, like gold, is an excellent conductor of heat and electricity. Silver may also be hammered into a very thin strip, much like tinfoil.
Why would sand cool faster than water in the dark?
The specific heat capacity of sand is much less than that of water. Hence sand cools earlier.
