Answer:
T₂ = 218.75 K
Explanation:
Given data:
Initial volume = 20 L
Initial pressure = 16 atm
Initial temperature = 500 K
Final temperature = ?
Final volume = 35 L
Final pressure = 4 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
by putting values,
P₁V₁/T₁ = P₂V₂/T₂
T₂ = P₂V₂ T₁/ P₁V₁
T₂ = 4 atm × 35 L × 500 K / 16 atm × 20 L
T₂ = 70000 atm .L. K / 320 atm.L
T₂ = 218.75 K
Answer: a) No, both are different.
b) Ramesh- 9.9%
Sarika - 10%
Explanation:
According to the solution prepared by Ramesh,
Mass of sugar he took (Solute) = 10 g
Mass of water he took (Solvent) = 100 g
Thus Mass % of the solution =
According to the solution prepared by Sarika,
Mass of sugar she took (Solute) = 10 g
Mass of Solution she took = 100 g
Thus Mass % of the solution =
Explanation:
Non-renewable energy sources CAN EVENTUALLY BE USED UP.
Non renewable energy sources refer to those energy sources that can not be replenished. Once they are used up, new one can not be formed or produced, this is because they can only be formed by natural processes and these processes take millions of years to occur. Examples of non renewable energy sources are: coal, natural gas and oil. All the fuels obtained from fossils are non renewable in nature.

Answer:
Oxygen
Explanation:
· Air decolorization makes use of chromophores’ instability on oxygen to decolorize the oil by air-oxidizing pigments. For example, the carotenoid and chlorophyll in the oil are very unstable because of their structure, which is easy to be discolored under the action of oxygen. However, air decolorization leads to thermal oxidation of the oil, too.
