please answer step by step with correct sig figs and units: You have 12.0 mol of a diatomic ideal gas at 300 K, and 4.00 kJ of heat to add to it. You can choose to heat it isochorically or isobarically. Which of these two methods will result in a higher final temperature, and what will that final temperature be in Kelvin?
please answer step by step with correct sig figs and units: 4) The mass of a helium atom is 4.003 atomic mass units. The mass of an argon atom is 39.95 atomic mass units. The root-mean-square speed Vrms of a certain sample of monatomic helium gas is 1920 m/s. What is the root-mean-square speed yes of a sample of monatomic argon gas at the same temperature?
please answer step by step with correct sig figs and units: 5) A cylindrical iceberg of uniform density with a height of 210. meters and a radius of 470. meters floats in the ocean with its axis oriented in the vertical direction. The iceberg extends 22.0 meters above the surface of the ocean. The density of seawater is 1030 kg/m. What is the density of the iceberg? Note that depending on conditions, ice typically varies between about 910 kg/m' and...
given the information answer Common constants: 9.81 m/s2 = gravity on Earth's surface 343 m/s = speed of sound (air @ 20°C) 1440 m/s = speed of sound (water @ 20°C) 1.21 kg/mp = air density (20°C, 1 atm) 998 kg/m3 = water density (20°C, 1 atm) 1 atm = 1.01 x 105 Pa 3 x 108 m/s = c = speed of light (vacuum) 1.661x10-27 kg = p = atomic mass unit Specific Heats: 2040 J/(kg °C) Cwater =...
A chemist dissolve a 13.4 g sample of KOH in 115.0 grams of water in a coffee cup calorimeter. When she did so, the water temperature increased by 23.8 °C. How much heat energy was required to dissolve the sample of KOH? Calculate the heat of solution in kJ/mol. Assume the specific heat of the solution is 4.184 J/g ·°C. please help with work shown. sci notation and correct sig figs as well
