Standard atmospheric pressure is 101.3 kpa. according to the graph, which of these four liquids boils at the lowest temperature?

The graph is attached...

The normal boiling point is the temperature at which the vapor pressure of liquid is equal to atmospheric pressure which is here 101.3 kPa

We have here 4 liquids from 1 to 4 and from the curve we can see that liquid 1 is reached to 101.3 kPa first at lower temperature which is: 35°C

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
