Given :

Mass of granite , m = 20 g .

Change in temperature , \Delta T=29-10=19^oC.

Specific heat capacity of granite , C=0.79\ J/g^oC .

To Find :

The heat absorbed by granite .

Solution :

We know , heat absorb is given by :

\Delta H=mC\Delta T\\\\\Delta H=20\times 0.79 \times 19 \ J\\\\\Delta H=300.2\ J

Therefore , heat absorb is 300.2 J .

Hence , this is the required solution .

at standard pressure, what is the temperature at which a saturated solution of NH4Cl has a concentration of 60g NH4CL/100 g H2O
Nataliya [291]

Answer: Temperature = T, unknown

Saturated Solution, NH4Cl concentration = 60g/100g H2O = 0.6g NH4Cl/g H2O

Assume density of H2O = 1 g/ml

m = 0.6g NH4Cl/g H2O / 1 g/ml

m = 0.6g NH4Cl/ml

See the table of saturated solutions and identify the temperature at which the concentration of NH4Cl is 60g/100g H2O.

Explanation:  The line on the graph on reference table G indicates a saturated solution of NH4CL as a concentration of 60. g NH4 Cl/100. g H2O

What happens to the pressure of a gas inside a rigid container if the temperature of a gas decreases?
NikAS [45]

Answer:

If the temperature of gas is decreased the pressure will also goes to decrease.

Explanation:

The pressure and temperature have direct relation. If the temperature of gas will increase the pressure of gas will also goes to increase.

According to the Gay-Lussas's Law,

The pressure of given amount of gas is directly proportional to the absolute  temperature when volume is kept constant.

Mathematical relationship:

P ∝ T

P = kT

P/T = k

and

P₁/T₁ = P₂/T₂
