Joleen wants to find out if the amount of sunlight a plant gets will affect its growth. To find out Joleen gets three of her mother’s plants; a fern, a violet, and a cactus. Then Joleen puts all three plants out on the front porch. Joleen checks the plants once or twice a week for three weeks. At the end of three weeks she notices that the cactus looks the same, the fern is a little brown, and the violet is nearly dead. Joleen decides that sunlight does not affect the growth of a plant. 1. Describe three things that Joleen did wrong.
2. Write a procedure describing the correct way for Joleen to find out if the amount of sunlight a plant gets will affect its growth.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
