Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.

What mass of water could be warmed from 21.4 degrees celsius to 43.4 degrees celsius by the pellet dropped inside it? Heat capac

Artist 52 [7]

42.34 g of water could be warmed from 21.4°C to 43.4°C by the pellet dropped inside it

Heat loss by the pellet is equal to the Heat gained by the water.

$q_{w} = -q_{p}$ ….(1)

where, $q_{w}$ is the heat gained by water

$q_{p}$ is the heat loss by pellet

$q_{w}$ = mCΔT

where m = mass of water

C = specific heat capacity of water = 4.184 J/g-°C

ΔT = Increase in temperature

ΔT for water = 43.4 - 21.4 = 22°C

$q_{w}$ = m × 4.184 × 22 …. (2)

Now

$q_{p}$ = $H_{c}$ ×ΔT

where $H_{c}$ = Heat capacity of pellet = 56J/°C

Δ T for pellet = 43.4 - 113 =- 69.6°C

$q_{p}$ = 56 × -69.6 = -3897.6 J

From equation (1) and (2)

-m× 4.184 × 22 =-3897.6

m= 42.34 g

Hence, 42.34 g of water could be warmed from 21.4 degrees Celsius to 43.4 degrees Celsius by the pellet dropped inside it.
