Which statement best describes what will occur if enough thermal energy is removed from the system to cause a cha А Molecular energy will decrease, and the substance will change from a gas to a liquid.
B
Molecular energy will increase, and the substance will change from a gas to a liquid.
C
Molecular energy will decrease, and the substance will change from a liquid to a gas.
D
Molecular energy will increase, and the substance will change from a liquid to a gas.

А Molecular energy will decrease, and the substance will change from a gas to a liquid.

Explanation:

The right choice is that molecular energy will decrease for the system and the substance will change from a gas to a liquid.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
