Direction: Read and analyze each statement carefully. Write "TRUE" of the statement is correct and "FALSE" If the statement is incorrect. Write your answer on the space provided True 1. Boiling point is the temperature by which the vapor pressure of the liquid is equal to the atmospheric pressure exerted into it. 2. When water vapor collides with air particles, the atmospheric pressure increased 3. Pure substances are made up of only one type of element or compound 4. The boiling point of a pure substance is fixed. 5. The boiling point of a liquid substance is used to determine whether the substance is pure or not 6. Atmospheric pressure is the force exerted on a surface by the air above it as gravity pulls it to Earth 7. The boiling point of a pure substance does not remain the same even if it is exposed to higher amount of heat 8. Melting point is the temperature at which matter begins to change from liquid state to solid state 9. Iron is an example of pure substance which has a high melting point 10. During melting homogeneous mixture has some portions that seem to be not melting
