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:
Acids
Explanation:
Acids are ionic compounds that produce positive hydrogen ions when dissolved in water. Acids taste sour. They conduct electricity when dissolved in water. They also react with metals to produce hydrogen gas.
Answer:
It is a mixture
Explanation:
It is a mixture because a mixture contains tow or more elements
But a compound is made up of atoms
