At high speeds, there is more kinetic energy involved - more energy that will be converted to other forms of energy. This includes breaking a car, or body parts of people involved.
Answer:
Freezing point solution = 70.131 °C
Explanation:
Step 1: Data given
Molality = 1.468 molal
A solution is created by dissolving biphenyl (C12H10) into naphthalene
Biphenyl is a non-electrolyte
Freezing point of naphthalene = 80.26 °C
Step 2: Calculate the freezing point depression
ΔT = i*Kf*m
⇒with ΔT = the freezing point depression = TO BE DETERMINED
⇒with i = the van't Hoff factor of biphenyl = 1
⇒with Kf = the freezing point depression constant of naphthalene = 6.90 °C/m
⇒with m = the molality = 1.468 molal
ΔT = 1 * 6.90 °C/m * 1.468 °C
ΔT = 10.13 °C
Step 3: Calculate the freezing point of the solution
ΔT = 10.13 °C
Freezing point solution = freezing point naphthalene - 10.13 °C
Freezing point solution = 80.26 °C - 10.129 °C
Freezing point solution = 70.131 °C
Answer:
the total electron that can be in the n=4 orbital is 32
Explanation:
it is because the formula is 2n^2,if n=4then it is 2(4)^2=32
Increases as well. More heat means more energy is being supplied.
