How does water’s high specific heat capacity affect large lakes? a. the water in the lakes changes temperature quickly. b. the water at the bottom of a lake will never freeze. c. the water from lakes evaporates quickly. d. the water in a lake changes temperature slowly.

D. The water in a lake changes temperature slowly.

Explanation: Specific heat is the amount of heat required to raise the temperature of 1 gram of substance through .

Evaporation is the process in which liquid state is changed to gaseous state at any temperature.

Water has high specific heat due to the presence of strong hydrogen bonds which requires large amount of heat to raise the temperature of water. Thus the molecules will not be able to gain enough kinetic energy and thus temperature changes slowly.

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
