What do pneumatic tools run on? compressed air manual pumping action vaporized gas fluid pressure

## Step 1<br />Pneumatic tools are a type of power tool that is powered by compressed air. This is a type of gas that is stored under pressure and can be used to power various tools. <br /><br />## Step 2<br />The compressed air is stored in a tank and is used to power the tool. This is different from manual pumping action, which is a method of powering a tool by manually pumping air into it. <br /><br />## Step 3<br />Vaporized gas is not a correct answer because pneumatic tools do not run on vaporized gas. <br /><br />## Step 4<br />Fluid pressure is also not a correct answer because pneumatic tools do not run on fluid pressure. <br /><br />## Step 5<br />Therefore, the correct answer is compressed air.
