Water freezes at 0 celisus. if a temperature drop is causing a glass of water to freeze, how would a thermometer in the water most likely change as the water freezes?
a. the temperature would keep rising steadily. b. the temperature would keep falling steadily. c. the temperature would fall to 0 celisus and stay there until all the water froze.
d. the temperature would not change or would change unpredictably

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
