The pistons in an engine show how gas behavior can be applied to everyday events. volume, temperature, and pressure of a gas are all involved in the working of pistons. which two statements show how these factors are related in pistons according to charles' law and boyle's law? a. as temperature increases, pressure increases. b. when the temperature is raised, volume increases. c. the piston moves up, decreasing volume and increasing pressure. d. volume remains constant whenever either pressure or temperature changes.

The correct answer is B when the temperature is raised,volume is raised and C The piston moves up,decreasing the volume and increasing the pressure.

Explanation:

According to Charles"s law in a fixed pressure constant mass of a gas"s volume is directly proportional to the temperature.Which means Volume of a gas increases with increase in temperature and volume of a gas decreases when temperature is lowered.

   So the charles"s law fits the statement B when the temperature is raised volume is raised.

According to Boyle"s law in a fixed temperature constant mass of a gas"s volume is inversely proportional to pressure of that gas.Which means increase in  volume occur by lowering the pressure and volume decreases when pressure increases.

  So The Boyle"s law fits the statement C the piston moves u,decreasing the volume and increasing pressure.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
