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.

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 = 
V₂ =
= 0.39L
