Apiece of metal weighing 57.3 g is heated to a temperature of 88.0°c and is then immersed in 155 g of water at a temperature of 21.53°c. after equilibration the temperature is 24.72°c. if ch2o = 4.184 j/g°c, what is cmetal?

a) .370 j/g°c

b) .164 j/g°c

c) 1.00 j/g°c

d) 2.11 j/g°c

e) .571 j/g°c

The specific heat capacity of the metal piece is .

Explanation:

The heat given by the hot body(metal pace) is equal to the heat taken by the cold body(water).

where,

= specific heat of metal = ?

= specific heat of water =

= mass of metal = 57.3 g

= mass of water = 155 g

= final temperature of water =

= initial temperature of metal =

= initial temperature of water =

Now put all the given values in the above formula, we get

The specific heat capacity of the metal piece is .

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
