What type of weather does low air pressure bring

Bad weather

Explanation: In a low pressure system warm air pushes up and replaces the cooler air as it sinks down. The air temperature increases which makes more space for water vapor to occupy so the humidity increases as well. Higher humidity means more amount of water vapor which forms clouds resulting into bad weather.

h

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.
