The specific heat capacity of oxygen is 918 J/kg °C. The specific heat capacity of water is 4181 J/kg °C. Which substance will r
Vsevolod [243]

Answer:

Water

Explanation:

Given the specific heat of oxygen is 918J/kg°C and the specific heat of water is 4181 J/kg°C.

Consider 1Kg mass of each substance.

Now 1 Kg of oxygen needs 918 J of energy to raise its temperature by 1°C

Also 1 Kg of water needs 4181 J of energy to raise its temperature by 1°C.

Clearly water recquires more energy when compared to oxygen.

Basically specific heat capacity is the amount of energy recquired to raise the temperature of a 1 kg body by 1°C.

if a gas has a volume of 2.60 L at a pressure of 1.60atm, what will its new volume be at a pressure of 10.6 atm
cricket20 [7]

Answer:

0.39L

Explanation:

Given parameters:

Initial volume of gas V₁ = 2.6L

Initial pressure on gas P₁ = 1.6atm

Final volume of gas V₂ = ?

Final pressure on gas P₂ = 10.6atm

Solution

Applying Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

Mathematically;

                      P₁V₁ = P₂V₂

                      V₂ = \frac{P_{1}V_{1} }{P_{2} }

                      V₂ =  \frac{1.6 x 2.6 }{10.6 } = 0.39L
