Question

Calculate the amount of heat required to raise the temperature of 1 kg of iron through 10°C​

Answer 1

Answer:

The amount of heat required to raise the temperature of a substance is determined by the following equation:

Heat (J) = mass of substance (g) x heat capacity of substance (J/g.K) x the change in temperature (K).

In this case the heat required = 1000 x 0.45 x 10 = 4500 J or 4.5 kJ

Answer 2

Required Answer:-

This can be calculated by the given equation:

$\large{ \boxed{ \boxed{ \sf{Q = mc∆T}}}}$

Where,

• Q: amount of heat required
• m: mass (in g)
• c: heat capacity of the substance (for iron, c= 0.45) unit: J/g.K
• ∆T: change in temperature. (in K)

Put the values and find the answer,

Q = 1000 × 0.45 × 10 (change is same in °C and K)

Q = 4500 J or 4.5 kJ

Note:-

• Take care of the units.
• Use the units that is followed and concert the rest.
• Change is same in celsius and Kelvin temperature scale$.$
