Answer:

700 kilo calories was burnt during the entire race.

172.41 grams of pasta would provide him with 700 kcal energy.

Explanation:

Rate of burning calories = R = 10 kcal/min

Number of calories burnt in 1 hour and 10 minutes = x

Duration of race = t =  1 hour + 10 min

1 hour = 60 minutes

t = 60 min + 10 min = 70 min

x=R\times t=10 kcal/min\times 70 min=700 kcal

700 kilo calories was burnt during the entire race.

Number of calories in 1 gram of pasta = 4.06 kcal/g

Amount of pasta with 700 kcal = m

m\times 4.06 kcal/g=700 kcal

m=\frac{700 kcal}{4.06 kcal/g}=172.41 g

172.41 grams of pasta would provide him with 700 kcal energy.

Calculate the heat released when 25.0 grams of water freezes at 0 degree Celsius.
mafiozo [28]

Answer:

= 8350 joules

Solution and explanation:

  • The heat of fusion refers to the quantity of heat released when a given amount of water freezes.
  • For example, 1 g of water releases 334 J when it freezes at 0°C.

Therefore; For 25.0 g of water.

Heat released = Mass of water × heat of fusion

                        = 25 g × 334 J/g

                        = 8350 Joules

Hence, the amount of heat released when 25.0 g of water freezes at 0°C is 8350 J.
