When it is filled with Helium it will expand and become more dense in the hot car. But when it becomes dense the gas molecules fly around in different directions, they collide with other objects and create pressure which can cause the balloon to pop.
This would be true.
The reason why this answer would be true is because a fossil's position in the rock layers determine how long they died and were preserved. If the fossils were right next to each other, then that means both organisms were preserved at the same time.
Answer:
Temperature is an intensive property, while heat is an extensive property. An intensive property means that the amount of substance present will not change the specific trait. Calorimetry, heat of fusion and heat of vaporization calculations.
The answer is; Relative dating
This type of dating is not concerned with determining the absolute age of rock. It compares between rock layer and determines which is younger or older in comparison. Therefore relative dating is significant in arranging geologic events based on the stratigraphy of rock layers.
