When gases in containers are heated, their molecules increase in average speed. This means that they exert a greater force when they collide with the container walls, and also collide with the walls more frequently. The gas is therefore under greater pressure when its temperature is higher.

Answer:
B) A drawn bow is released, causing an arrow to fly across the field
Explanation:
Potential energy can be thought of as "potential" to do something. For eg, putting a ball on top of hill causes the ball to have the potential to roll down the hill if released. Here the ball converts the potential energy into kinetic energy (energy of motion) to roll down.
Similarly, the bow has been stretched (potential to fly if released), and when its released, it converts the potential energy into kinetic energy.
Answer:
Alchemy
Explanation:
Alchemy is the believe that base metals such as a copper, lead etc can be transmuted into gold.
The alchemists were in search of a magical piece that would enable them to make gold from base metals. They called this magical stuff 'the Philosopher's Stone'.
Modern science has discovered that lead can be turned into gold,without applying the methods of alchemy. Nuclear transmutation in particle accelerators can indeed change one element into another.
