How much heat do you need to raise the temperature of 150 g of ice from −30 °c to −15 °c ?

Answer : The amount of heat needed is, 9405 J

Explanation :

Formula used :

or,

where,

Q = heat required = ?

m = mass of ice = 150 g

c = specific heat of water =

= initial temperature  =

= final temperature  =

Now put all the given value in the above formula, we get:

Therefore, the amount of heat needed is, 9405 J

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
