Question

question 10. which of the following statements are true regarding the role of energy in physical and chemical changes? (select all that apply.) energy is always involved when physical or chemical changes occur. energy can only be in the form of heat during physical and chemical changes. heat can provide enough energy to cause both physical changes (such as melting) and chemical changes (such as the decomposition of water vapor to form oxygen gas and hydrogen gas). light is one of the forms of energy that can be involved in physical and chemical changes. energy involvement is only necessary for chemical changes and not for physical changes.

Explanation:

Answer:

Energy is always involved when physical or chemical changes occur.
Heat can provide enough energy to cause both physical changes (such as melting) and chemical changes (such as the decomposition of water vapor to form oxygen gas and hydrogen gas).
Light is one of the forms of energy that can be involved in physical and chemical changes.
