What is the amount of heat required to raise the temperature of 200.0 g of aluminum by 10°C? (specific heatof aluminum = 0.21 ca
ELEN [110]

Answer:

We need 420 cal of heat

Explanation:

Step 1: Data given

Mass of the aluminium = 200.0 grams

Temperature rises with 10.0 °C

Specific heat of aluminium = 0.21 cal/g°C

Step 2: Calculate the amount of heat required

Q =m * c* ΔT

⇒with Q =  the amount of heat required= TO BE DETERMINED

⇒with m = the mass of aluminium = 200.0 grams

⇒with c = the specific heat of aluminium = 0.21 cal/g°C

⇒with ΔT = the change of temperature = 10.0°C

Q = 200.0 grams * 0.21 cal/g°C * 10.0 °C

Q = 420 cal

We need 420 cal of heat (option 2 is correct)
