1. If I double the temperature (in K) of a balloon, the volume of the balloon a) doubles b) halves c) stays the same 2. If I mix 3.0 mol of N2(g), 2.0 mol of Cl2(g), 4.0 mol of O2lg) and 1.0 mol of H2(g), what is the mole fraction of O2(g)? If the total pressure is 2.00 atm, what is the partial pressure of O2(g)? (Hint-the answer for mole fraction of O2(g) and the answer for partial pressure of...
Consider a balloon that has a volume V. It contains n moles of gas, it has an internal pressure of P, and its temperature is T. If the balloon is heated to a temperature of 15.5T while it is placed under a high pressure of 15.5P, how does the volume of the balloon change? It doubles. It stays the same. It increases greatly. It decreases slightly.
You are playing with a helium balloon on a warm Colorado day. Suddenly, the Celsius temperature doubles. Which of the following is true? a. The volume of the balloon will double. b. The pressure inside the balloon will double. c. The actual temperatures are needed to answer this question. d. The volume of the balloon will slightly increase. e. The volume of the balloon will decrease.
Can you answer these questions about gases and explain your reasoning? 1.If I heat an enclosed volume of gas so that its Kelvin temperature doubles, what happens to the average speed of the molecules in the gas? A. It more than doubles. B. It doubles. C. It increases by between 50% and 100%. D. It increases but by less than 50%. E. It stays the same 2. If I heat air in an air balloon so that its Kelvin temperature...
A balloon with an initial volume of 3.5 L at a temperature of 294 K is warmed to 365 K . What is its volume at the final temperature? (Assume constant pressure.) Express your answer using two significant figures.
1) A balloon has a volume of IL at 20°C and 101.325 kPa of Pressure. If the pressure stays constant but the temperature increases to 45°c, what will the volume of the balloon be?
A balloon is filled to a volume of 7.45 x 102 mL at a temperature of 15.0°C. The balloon is then cooled at constant pressure to a temperature of 1.32 x 102 K. What is the final volume of the balloon? Volume = mL
1) A balloon has a volume of 1L at 20°C and 101.325kPa of pressure. If the pressure stays constant but the temperature increases to 45°C what will the volume of the balloon be? 2) Determine the volume occupied when 40g of Oz is at 30°C at standard pressure.
1) A weather balloon filled with He gas to a volume of 262 L on a day when the temperature was 18°C. The balloon was only released the next day when the temperature was -10°C. Calculate the new volume of the weather balloon. Assume that the atmospheric pressure remained the same on both days. 2) The volume of an empty flask with a one-holed stopper was 285 ml (V1). You heated the flask for 1 minute (T1) and then cooled...
