True or false When heat flows to an object, it can change states.
emmasim [6.3K]

Answer: True

Explanation:

The matter exists as solid, liquid or gas. These are called the states of matter. The change of matter from one state to another can be achieved by heating or cooling.

The solid state can be converted into liquid state by providing heat to solid. The heat will make the particles move farther, resulting into liquid state.

Similarly when liquid state is provided heat, it changes to gaseous state. The heat will make the particles move much more faster.

Thus the statement that when heat flows to an object, it can change states is True.

A solution contains 15 grams of salt per litter of solution. How many grams of salt are in 3.3 litters of solution?​
Verizon [17]

49.5g

Explanation:

Mass of salt = 15g

Volume of solution = 1L

Volume of given solution = 3.3L

Unknown:

Mass of salt in the solution = ?

Solution:

Since we have been given the concentration of the salt in the solution, we can use it to solve the problem.

Concentration; 15g/L

Given;

    In 1L of the solution we have 15g of salt,

In    3.3L of the solution we will have 3.3 x 15 = 49.5g

The salt is the solute and it represents the dissolved substances.
