Question

A large bottle containing 845 g of water at 5 ∘C is removed from the refrigerator.
Part A
How many kilojoules are absorbed to warm the water to room temperature of 22∘C?

 

Can't understand this topic. Please and thanks!

Answer 1

Q = heat transfer

 

Q = mcΔT

 

m = mass of water = 845 g

 

c = specific heat of water (look it up in your chemistry book in appropriate units)

 

ΔT = temperature change = (22 - 5)°C

 

Plug in the numbers and get Q in the appropriate units.
