Determmine value of k such that
Kx+y+z=1
X+ky+z=1
X+y+kz=1 has a) no solution b) unique solution c) more than one solution
You are given m*n matrix and k write a program to compute the area of submatrix
A piston–cylinder device contains 1.2 kg of nitrogen gas at 120 kPa and 27°C. The gas is now compressed slowly in a polytropic process during which PV1.3 = constant. The process ends when the volume is reduced by one-half. Determine the entropy change of nitrogen during this process.
An electron and a positron are moving side by side in the +x direction at 0.500c when they annihilate each other . Two photons are produced that moves along the x axis (a) Do both photons move in the +x direction ? (b) What is the energy of each photon
Can a solution be saturated but dilute? If yes give example?
Give 2 examples of a process in which the Entropy of the system decreases but the entropy of the Universe increases.
Derive Gibb’s-Helmholtz Equation.

A shifted to right by 1 b
If abc shifted to ijk according to input is yes other wise no
What should be the ratio of concentrations of acetic acid and acetate ions to have a solution with pH 5.74? [pKa for acetic acid is 4.74].
