Question

g A 28.4 g sample of an unknown metal is heated to 39.4 °C, then is placed in a calorimeter containing 50.0 g of water. Temperature of water increases from 21.00 °C to 23.00 °C. What is the specific heat of this metal in this problem?

Answer 1

Step-by-step explanation:

water then

The heat lose by aluminum = The heat gain by the water.

Q₁=Q₂

Where,

Q = m ×s× ΔT

m= mass of an object

s= specific heat of the
