What does a decrease in temperature indicate about the molecules in a sample of liquid water? (3 points)
group of answer choices
decreased kinetic energy of the molecules
decreased chemical energy of the molecules
increased chemical energy of the molecules
increased kinetic energy of the molecules

Decreased kinetic energy of the molecules

The first option that is given in the question is the correct option.

Explanation:

The molecules of a substance act differently at different temperatures but we know that its energy is dependent on the temperature at which it is present. The normal tendency of molecules is to vibrate on move around but, when it absorbs a certain amount of heat it gains more energy and tends to move around faster.

And just the other way round happens when heat is lost so we can say with a decrease in temperature the activity of molecules will also decrease and hence the kinetic energy will be decreased.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
