A serving of Cheez-Its releases 947,000 J of energy when digested by your body. If this same amount of energy were transferred to 1750 g of water, what would the change in temperature be?

Respuesta :

Answer:

The change in temperature would be 129.3 °C

Explanation:

Step 1: Data given

947000 Joule of energy is released

Mass of water = 1750 grams

Specific heat of water = 4.184 J/g°C

Step 2: Calculate change in temperature

Q = m*c*ΔT

⇒ Q = the heat released = 947000 Joules

⇒ m = the mass of water = 1750 grams

⇒ ΔT = The change of temperature = TO BE DETERMINED

947000 J = 1750 grams * 4.184 J/g°C * ΔT

ΔT = 129.3 °C

The change in temperature would be 129.3 °C
