With work pls a beach ball is inflated to standard atmospheric pressure. a diver then takes the ball underwater to a depth of 25 meters, but its winter and the water is cold! the original volume at 1.0 atm is 25.8 L , and the air temperature is 23 C. total external pressure is 3.5 atm. calculate the new volume of the beach ball.

Two friends at different locations want to communicate with each other by sending low energy signals. which of the following methods can they use to communicate? a) produce x-rays using colliding electrons and send them to radios, which capture sound b) send messages using infrared radiation, which travel in the form of waves c) send radio waves through intervening media like radio and television d) produce sound waves using microwaves from heated objects

Neils bohr believed that electrons orbited the nucleus in different energy levels, based on strong support from

At 20°c, a sample of h2o liquid and a sample of co2 gas each have the same average kinetic energy. why is one a liquid and the other a gas at this temperature?
