Answer: A. The hydrogen bonds cause water to resist a change in temperature.

Explanation:

Heat of vaporization is defined as the amount of heat required to convert 1 mole of liquid to gaseous state.

Water has high heat of vaporization due to the presence of strong hydrogen bonds between  hydrogen and a electronegative element oxygen. As the water molecules are strongly bonded to each other, large amount of heat is required to raise the temperature of water.

The molecules will not be able to gain enough kinetic energy and thus temperature changes slowly.

Macy has hired 400 store sanyas. If each Santa sees 125 children a day for 30 days, how many children are seen by mac's santa
Pachacha [2.7K]
So here let's first find the amount of children every santa, in total, sees in one day. So if there are 400 santas, and each sees 125 children, you can just multiply 400 by 125 to see how many children all the Santas see in one day.

400 * 125 = 50,000

Now, since there are 30 days which all the santas see 50,000 children, you can then multiply 30 by the 50,000 children to get how many children are seen by Macy's Santas in a month.

30 * 50,000 = 1,500,000

So 1,500,000 children are seen by Macy's Santas.
