What method is used to find the number of neutrons in an atom? a
rounded atomic mass - atomic number = number of neutrons

b
atomic number - rounded atomic mass = number of neutrons

c
atomic number - electron number = number of neutrons

d
electron number - atomic number = number of neutrons

Apersons beliefs and general outlook, which act like filters on the information they receive are called ?

A15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°c to 175°c. what is the specific heat capacity of iron?

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
