Energy main article Energy is the ability to create a change, for example, creating motion. Tasks (like lifting a box) require an amount of energy to complete.
Explanation:
Answer : The specific heat of metal is 
.
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of metal = ?
= specific heat of water = 
= mass of metal = 129.00 g
= mass of water = 45.00 g
= final temperature = 
= initial temperature of metal = 
= initial temperature of water = 
Now put all the given values in the above formula, we get
Therefore, the specific heat of metal is .
Answer:
B
Explanation:
The warmer the water, the more space it takes up, and the lower its density.
10.0gNaCl/2.0Lsolution= 5.0g/L
