A sealed, rigid cylinder is filled with 10 mL of oxygen gas at 25°C and a pressure of 1.00 atm. The temperature is then doubled. How do the number of molecules of gas before the increase in temperature compare to the number of molecules after the temperature is increased?

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
