What is the effect of increase of pressure on the solubility of a gas in liquid ?

The melting points of most of the solid substances increase with an increase of pressure acting on them. However, ice melts at a temperature lower than its usual meiting point, when the pressure increases. This is because:

When 80 litres of a gas at 27^@C and 10 atmospheres is reduced to 50 litres by increasing the pressure, the temperature increases to 37^@C . What is the final pressure on the gas assuming it to be ideal ?

Assertion : Tobacco contains a large number of alkaloids including nicotine. Reason : Nicotine stimulates adrenal glands which decrease blood pressure and increase heart rate.
