What change would you expect in the characteristic of a musical sound when we increase its frequency at one instance and amplitude at another instance?

What characteristics do you expect from an electrondeficient hydride with respect to its structure and chemical reactions?

For an ideal gas, C_(V)=(3)/(2)R . (a) What will be the change in internal energy (DeltaU) of 1 mole of an ideal gas if its temperature is increased by 4K at constant volume ? What would be DeltaU if the temperature of this gas is increased by the same amount of constant pressure? keeping pressure constant if the temperature of that same amount of gas is increased by 4K then what will be the change in internal energy (DeltaU) of that gas? (c) give reason for different values of DeltaU and DeltaH ?

What will be the change in the resistance of the Eureka wire,when its radius is halved and length is reduced to one-fourth of its original length?

A train moving with a velocity v is passing a station. A passenger standing on the station notices that the whistle emitted by the train changes its frequency by 50 Hz when it passes him. Given that the frequency of the whistle when the train is at rest with respect to the passenger is 500 Hz and the velocity of sound in air is 330 m/sec, the velocity of the train is

What do you mean by the compresiblity factor of a real gas? What is its value for an ideal gas? When does its value for a real gas become greater than, less than or equal to one?
