Question

When two substances are mixed, they might form a new substance. Which of the following would indicate that a new substance has been formed?

The temperature of the mixture decreases
The volume of the mixture increases
The mass of the mixture increases
One of the substances dissolves

Answer 1

When two substances are mixed and a new substance is formed, it can be indicated by changes in temperature, volume, mass, or dissolution of one of the substances.

Step-by-step explanation:

When two substances are mixed, the formation of a new substance can be indicated by several observations. One such observation is a change in temperature. If the temperature of the mixture decreases or increases significantly, it can suggest the formation of a new substance. Another indication is a change in volume. If the volume of the mixture increases or decreases significantly, it can be a sign of a new substance being formed. Additionally, the formation of a new substance can sometimes result in a change in mass. If the mass of the mixture increases or decreases due to a chemical reaction, it can indicate the presence of a new substance. Lastly, if one of the substances dissolves completely in the mixture, it could be an indication of the formation of a new substance.
