Given an n x m matrix and a dictionary containing k distinct words of length between 1 and 30 symbols, the word search should return all the words you can get from the matrix that are contained in the dictionary. there are rules: you can start from any cell in the matrix and go up, down, to the left, and to the right (not leaving the matrix) to collect letters for the word. your "path" should not cross itself, i. e., a cell in the matrix cannot be visited more than once. you need to return the array of words found. there is no need to return the "paths" for them.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
