B. water will boil at a lower temperature on Venus than on Earth.
Explanation:
Because temperature and pressure are directly proportional... increase in pressure will increase in the atmospheric temperature.... Venus has higher pressure than earth that also means it has higher atmospheric temperature and as the temperature is already high the water will require lesser heat to boil
Answer:
During the fractional distillation of crude oil: heated crude oil enters a tall fractionating column , which is hot at the bottom and gets cooler towards the top. vapours from the oil rise through the column. vapours condense when they become cool enough. liquids are led out of the column at different heights.
Nitrogen is often used for the storage of semen samples for artificial insemination of cattle. Nitrogen is used to maintain a dry inert atmosphere over chemicals during storage, reaction or processing. Used in brewing, soft drinks and wine-making industries to exclude air from the product and de-aerate water.

Answer:
4 g/mL
Explanation:
The density of a object can be found using the following formula.
where m is the mass and v is the volume.
We know that the mass of the object is 24.0 grams and the volume is 6.0 milliliters.
Substitute the values into the formula.
Divide 24 g by 6 mL.
The density of the object is 4 grams per milliliter.
