a cube of iron was heated to 70C and transferred to a beaker containing 100g of water at 20c the final temperature of the water and the iron was 23c what are the heat capacaty

Complete question:

a  cube of iron was heated to 70C and transferred to a beaker containing 100g of water at 20c the final temperature of the water and the iron was 23c what are the heat capacity of iron and water ?

The heat capacity of iron which is equal to heat capacity of water is 1254 J.

Explanation:

Given;

initial temperature of the iron, t₁ = 70 °C

mass of water, m₂ = 100 g

initial temperature of water, t₂ = 20 °C

final temperature of the mixture, t = 23 °C

The heat lost by iron =  heat gained by water

Thus, the heat capacity of iron = heat capacity of water

Heat gained by water is given by;

Q = mcΔθ

Q = mc(t - t₂)

where;

c is the specific heat capacity of water = 4.18 J/g°C

Q = (100 )(4.18)(23 - 20)

Q = 1254 J

Therefore, the heat capacity of iron which is equal to heat capacity of water is 1254 J.

c) up is the direction the magnetic force is acting on the charge.

the answer to this is proletariats.

hope this : )
