I am not sure how you want me to answer this, but yes, gas can go from being a gas to a liquid when the right temp and pressure is applied.
Newton's 2nd law of motion: Force = (mass) x (acceleration)
Divide each side by (mass) : Acceleration = (force) / (mass)
Acceleration of the truck = (4,200 N) / (2,000 kg) = 2.1 m/s²

What is negative end?
The grounded connection of a car battery is called a negative terminal, and it is typically identified by a minus (-) sign. Typically, it is black and color-coded. The other terminal is a positive terminal that is typically color-coded red or orange and denoted by a plus (+) sign. The grounded terminal attaches to an object that is grounded on the car, usually a bolt in the chassis. The starter motor, as well as other switches, relays, and accessories, are connected to the positive terminal. The car won't start if the battery isn't properly grounded. These days, the majority of car batteries are packed with a charged acid solution that is very explosive and gaseous. In order to keep the battery's inner plates immersed, distilled water may occasionally need to be supplied to the fill-caps.

Answer:
Hysteresis, Eddy current, flux leakage and resistance of winding are those four reasons. It is impossible to overcome this four reasons, Hence transformer never be 100% efficient.
