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?

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

Changing the state of matter of a substance is a physical change. It is usually caused by

changing the temperature or surrounding pressure of a substance. Remember that we said that the

temperature of a substance is related to the speed of the particles' motion. The speed of the

particles determines the state of matter of the substance.
