If the temperature of a gas is 27.0°C when the volume is 1.25 L, what will the new volume be if the temperature is raised to 150°C?

Explanation:

0.17166666666

Explanation:

New volume V2 = 1.7625 L

Explanation:

Given:

Old temperature T1 = 27°C = 27 + 273 = 300 K

Old volume V1 = 1.25 L

New temperature T2 = 150°C = 150 + 273 = 423 K

Find:

New volume V2

Computation:

V1 / T1 = V2 / T2

1.25 / 300 = V2 / 423

New volume V2 = 1.7625 L

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
