If 1.0kg of juice of a specific heat capacity 3.0kj/kg degrees c at a temperature of 10 degrees celsius is poured into a 1.0kg glass bowl that is 15 degrees celsius. determine the final temperature of the juice.

We have heat lost by water is equal to heat gained by Juice.

Heat exchanged is calculated using the formula,

Let be the final temperature then,

The final temperature of the juice is 12.913 K.

i don't understand. explain it clearly

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
