Determine the change in specific internal energy for air from 350 K, 1 bar to 700 K and 2.5 bar. Determine the change in specific enthalpy of ammonia from 0.3 MPa and a quality of 0.4 to 0.3 MPa and 40oC. Determine the change in entropy for 2 kg of argon from 350 K, 1 bar to 700 K and 2.5 bar. Determine the change in specific energy for R-22 from 40oC, 16 bar, and 50 m/s to 40oC, 10 bar and 5 m/s.

Define the kinetic molecular theory

Which subshell is represented by the actinides family?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
