Answer:
V₂ = 520.42 mL
Explanation:
Given data:
Initial volume = 350.0 mL
Initial pressure = 840 mmHg
Initial temperature = 33°C (33 +273 = 306 K)
Final temperature = 52°C (52+273 = 325 K)
Final volume = ?
Final pressure = 600 mmHg
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 840 mmHg × 350.0 mL × 325 K / 306 K × 600 mmHg
V₂ = 95550000 mmHg.mL.K /183600 K.mmHg
V₂ = 520.42 mL
The heat from your hand would be absorbed by the (assumed) colder flask, since an endothermic reaction means that the reaction requires an absorption of heat as opposed to an exothermic reaction, which releases heat.

Explanation:
The human activity creating water pollution and depletion are uses of fertilizers, detergents and chloro flouro carbon many other things.
<h3>What is water pollution?</h3>
Water pollution is defined as the contamination of water bodies, usually as a result of human activity, in such a way that their lawful uses are harmed.
The activities of human that creating water pollution are:
- Uses of fertilizers
- Harmful chemical in agriculture
- Detergents for washing clothes
- Wastes from industries
And depletion in the ozone layer are due to halogen source gases, which contain chlorine and bromine atoms, are produced by human activities. These emissions into the atmosphere eventually contribute to ozone depletion in the stratosphere.
Hence human activities are uses of fertilizers, detergents and many other things.
