Question

question 1
select the best definition for each term.
law of conservation of energy
thermochemistry
a process in which heat is absorbed into the system, so the energy of the system increases
a process in which heat is released from the system, decreasing the energy of the system
energy cannot be created or destroyed, but can change in form
endothermic process
exothermic process

Explanation:

• Law of conservation of energy: Energy cannot be created or destroyed, but can change in form. This is a fundamental principle in thermodynamics.
• Thermochemistry: The study of heat associated with chemical reactions and physical processes. It focuses on the heat changes during these processes.
• Endothermic process: A process in which heat is absorbed into the system, so the energy of the system increases. For example, when ice melts (absorbing heat).
• Exothermic process: A process in which heat is released from the system, decreasing the energy of the system. For example, combustion reactions (releasing heat).

• Law of conservation of energy: Energy cannot be created or destroyed, but can change in form.
• Thermochemistry: The study of heat associated with chemical reactions and physical processes.
• Endothermic process: A process in which heat is absorbed into the system, so the energy of the system increases.
