If a gas has a volume of 150 mL when the temperature is 25.0°C, what is the temperature in°C if the volume increases to 200 mL?

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

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.
