Question

A student notices that after two chemicals are mixed together the temperature of the mixture is higher than the temperature of the individual chemicals. What type of process must have occurred?

a) exothermic
b) isothermic
c) endothermic

Answer 1

Answer: exothermic

EXPLANATION: any process in which heat energy is released is called an exothermic process. For example burning of wood produces heat, so combustion of wood is an exothermic process.

When chemicals were not mixed they were at room temperature and when we mix them exothermic reaction took place and heat was released which raised the temperature of mixture.
