Answer: Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant. with k being a proportionality constant that depends on the amount and pressure of the gas.
Explanation:
Answer:
Endothermic
Explanation:
Heat is retained while exothermic means heat is released
Averqge speed of the car = 45 miles/hr, which means,
The car travels 45 miles in 1 hr.
Using unitary method,
The car travels 45 miles in 1 hr
The car would travel 1 mile in 1/45 hrs
The car would travel 90 miles in 1/45×90 hrs
So, calculating this,
1/45×90 = 2 hrs
Answer:
302 kj heat is released by lowering the temperature
The answer would be "Gas".
