4. Calculate the heat energy needed to heat 25.0 g of water from 13.0°C to 18.0°C. Use chart above for specific heat of water. Use units and show all work.​

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
