7 0

Answer:

Explanation:

NASA wants to send astronauts to Mars, and they could do it with nuclear-powered rocket engines.

Answer:

Explanation:

you could do Water's Attraction to Other Polar Molecules.

Cohesion, otherwise known as water's attraction to other water molecules, is one of the big properties of water. Water's polarity lends it to be attracted to other water molecules. The hydrogen bonds in water hold other water molecules together. Due to water's cohesiveness:

Liquid water has surface tension. This allows for insects, such as Water Striders, to walk on water.

Water is a liquid at moderate temperatures, and not a gas.

Using an eye dropper and a coin, you can slowly keep adding water to the coin and you will see cohesion.

The water molecules will stick together and form a dome over the coin. Keep adding drops until the drop breaks and spills off of the coin. This is caused by gravity overcoming the force of cohesion.
