An 8.38 gram sample of water lost 870 J of heat. What is the change in temperature

Find the mass of a sample of water if its temperature dropped 24.8 degrees Celsius when it lost 870 J of. heat. (specific heat of water is 4.18 J/g x degrees Celsius) 8.38 grams. How many degrees would the temperature of a 450 g piece of iron increase if 7600 J of.

Explanation:

the answer is to check all of them! they all apply well at least i think so!

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
