(a) Explanation Temperature of earth’s atmosphere is 20.0 ° C , effective molar mass is 28.9 g / mol . Write the expression for Boltzmann distribution law. n V ( E ) = n 0 e − E / k B T (1) Here, n V ( E ) is the number of molecules per unit volume with energy between E and E + d E . n 0 isthe number density at sea level. T is the absolute temperature. k B is the Boltzmann constant (b) To determine The ratio of the atmospheric density there to the density at sea level.

Energy transfer

The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.

Molar Specific Heat

Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)

Thermal Properties of Matter

Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which…

One of Spider-Man’s less talked about powers is that he can jump really high. In the comics Spider-Man can jump upwards 3 stories. A) If Spider-Man leaves the ground at 14.3 m/s, how high can he get? y= B) If Spider-Man jumps directly upwards with the initial velocity used above and then returns to the ground, what total amount of time does he spend airborn? t=

An insulating rod is positively charged, and an electrically neutral conducting sphere is mounted on an insulating stand. The rod is brought near to the sphere on the right, but they never actually touch. Q. Select the image that best represents the resulting charge distribution on the conducting sphere.

This is a multi-part problem. For each part make sure to include sign to represent direction, with up being positive and down being negative.
