Given:
The heat content of the pizza is Q = 500 kcal
The volume of the cold water is V = 50 L
The mass of a liter of cold water is 1 kg.
Calculate the mass, M, of cold water.
M = (50 L)*(1 kg/L) = 50 kg
The specific heat of water is
c = 4.184 kJ/(kg-K)
Also,
1 kcal = 4184 J, therefore
Q = (500 kcal)*(4184 J/kcal) = 2.092 x 10⁶ J
Let ΔT = increase in temperature of the cold water, °C (same as K).
Then
Q = M*c*ΔT
or
ΔT = Q/(M*c)

Answer: The temperature increases by 10 °C (or 10 K)
Answer:
The increase in the human population and waste it produces, deforestation , peat bog destruction and global warming are all reducing biodiversity
Explanation:
Um. The drawbacks to the extensive use of solar energy? well all the other statements about it are false so the correct answer would have to be B. Necessary equipment and installation are expensive
hope that helped
