Answer:
Explanation:
specific heat of granite s = .79 J / g / k
let the mass of granite = m
heat lost by granite = heat gained by water
heat lost = mass x specific heat x drop in temperature
= m x .79 x (80 - 20.45)
heat gained by water
= 3000 x 4.186 x (20.45- 20)
heat lost by granite = heat gained by water
m x .79 x 59.55 = 3000 x 4.186 x .45
m = 120.12 g .
If the item or substance has changed into a state where you are able to change it back such as:
Water melting
Water freezing
I believe it is A because the plant is offering protection while the bacteria is converting it in to nitrogen that the plant can use!
The temperature of something.
