A group of 35 students attend a class in a room that measures 11 m by 8 m by 3 m. Each student takes up about 0.075
The mass of air can be obtained from the ideal gas law:
where P is the gas pressure, V is the volume of the gas, Mwt is the molecular weight of the gas (for air, 28.97 kg/kmol), and R is the ideal gas constant

- The specific heat of copper is 0.093 cal/(g.°C) and the specific heat of gold is 0.031 cal/(g.°C). If 9.5 cal is supplied to one gram of copper and one gram of gold, the RATIO of temperature increase of gold to that of copper is:arrow_forwardAn open vessel containing liquid water stands in a sealed room measuring 3.0m wide x 3.0m long x 3.0m high. The temperature of the room is 300K and, over time, some of the liquid water evaporates. Eventually, the liquid water level in the vessel stops changing. How many grams of water will be in the humid air within the sealed room? Show all workarrow_forward2.5 liters of water at 60 degree Celsius is placed in a freezer. What amount of mass in kilograms has not yet transformed into solid ice if only 80 percent of the total Heat was removed?arrow_forward
- One wall of a room measures 14 feet long and 8 feet high. It's contains a window 5 feet wide and 3.5 feet high. The wall has an R-Value of 15.5. the unit R-value of the window is 3.5. Find the rate of heat flow through the wall when the inside air temperature is 68 degrees Fahrenheit and the outside temperature is 5 degrees Fahrenheit.arrow_forwardThe data listed below is from a passenger hot air balloon. The balloon is designed to lift 10-people (80 kg each person). The balloon consists of a basket, a burner- propane tank system. It will lift up when the cold air trapped inside warms up by the burner. Density of air inside the balloon is 99°C: 0.9486 kg/m³, density of air outside balloon is 20°C (ambient): 1.2041 kg/m³ Mass (kg) Balloon Basket Burner Propane tank 113.4 kg 63.5 kg 22.7 kg 183.7 kg Assume the balloon is a sphere shape, volume =(4/3)pi R3. a. Determine the minimum diameter of the balloon that would have a total lifting force to balance the weight of balloon, basket, burner, propane tank and 10 people? b. If the balloon is converted to survey the weather, it will be filled with hydrogen gas (H2). Assume the weight of the people (800kg) is now replaced by onboard equipment, what is minimum diameter needed to keep it afloat at 18km above the surface of the earth?arrow_forwardA 10 kW drilling machine is used to drill a bore in a small aluminum block of mass 8 kg. How much is the rise in temperature of the block in 2.5 minutes, assuming 50% of power is used up in heating the block? (specific heat of aluminum : 0.91 J/(g °C))arrow_forward
- Max likes to drink tea. He uses his kettle to heat 1.6 liters of water from 18°C to 100°C every day. What does it cost him to heat the water per year (365 days) if he pays 29 cents per kWh of electricity. State the costs in euros to two decimal places. The material values of water averaged for the swept temperature range are: Cwater=4.18 kJ/(kg-K); pwater=983 kg/m3; Awater=0.654 W/(m2.
