Question

An insulated bottle contains 150 g of water at 4.0 Celsius. When 90 g of metal at 100 Celsius is placed into the cold water the temperature of both eventually becomes 21 Celsius. assuming no heat is lost to the container or the air, what is the specific heat capacity of the metal? *The specific heat capacity for water is 4200J/Kg°C

Answer 1

1506.33J/Kgc

Step-by-step explanation:

heat loss=heat gain

Qw=Qm

m1c1T1=m2c2T2

0.15×4200×(21-4)=0.09×c2×(100-21)

c2=1506.33J/Kgc
