Using Gay-Lussac's Law, pressure is proportional to (absolute) temperature in Kelvin. We first convert the temperature values to Kelvin: 110 C = 383.15 K, while 65 C = 338.15 K.
P1/T1 = P2/T2
22.5/383.15 = P2/338.15
P2 = 19.9 psi

Beth’s hygrometer is reading a temperature of 30°C and a relative humidity of 65%. The humidity in the air is how many grams/cub
emmasim [6.3K]
This is asking for the absolute humidity. So if the relative humidity is 65 % and the air temperature is 30 then we need to have in mind the barometric pressure which will be 760. The humidity in the air will be 0.020 kg/m3. In order to know this we calculate it eith the mass of water vapour in a unit volume of air. This is a measure of the actual water vapour content of the air. the for mula would go like this: AH = Mv / V.

Adiabatic process is a process in which _ is constant (a) temperature (b)volume (c)pressure (d) heat
fomenos

Answer: Adiabatic process is a process in which <u>heat</u> is constant

Explanation:

The processes in which temperature remains constant is called isothermal process.

The process in which Volume remains constant is called isochoric process.  

The process in which pressure remains constant is called isobaric process.

 The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.

Thus option d) heat is correct

Virty [35]

Answer:

4.3.

Explanation:

  • Measurements that are close to the known value are said to be accurate, whereas measurements that are close to each other are said to be precise.
  • The most closest measurement to the known value is 4.3 g.
  • So, the right choice is: 4.3 g.
