Boiling water. A phase change occurs when water boils.

The three common phases are solid, liquid, and gas. A phase change happens when one phase changes into different phase without a change in chemical composition.

When water boils, the liquid phase becomes a gas (water vapour or steam). The water does not change its chemical composition be each phase consists of water. Thus, boiling water involves a phase change.

Mixing paint does not involve a phase change because it stays a liquid during all stages of the mixing.

A suspension consists of two phases, but the phases do not change into other phases.

What is the volume in liters of 3.80 moles of CO2gas at STP?

pantera1 [17]

Answer:

V = 85.2

Explanation:

STP = 273K and 1 atm

Considering what we know about STP, we get the moles, temperature, and pressure. Using the ideal gas law we can find the volume (PV = nRT). Plug in our variables: (1 * V = 3.80 * R * 273). Since we are dealing with atm and not kPA or mmHg, we use the constant for atm (0.0821) which we use for R. (So.. now our equation is 1 * V = 3.80 * 0.0821 * 273). We now multiply the right side to get 85.17054. So... V = 85.2 considering sigificant figures (this is the part where I am the least sure of, since I havent done sig figs in a while)
