No, a heat engine is not a device that converts work into heat. It is the opposite, which means it is a device that converts heat into work.
Yes this is correct.
"Thermodynamics is the study of the relationships among heat, work and other forms of energy."

Sand needs least energy to increase the temperature as its specific heat is very low compared to that of water. Water needs more energy to increase its temperature as its specific heat capacity is higher.
2p + 11p + 5 = 13p + 5 which does not factor.
If the expression had been 2p2 + 11p + 5 then this can be factored,
2p2 + 11p + 5 = (2p + 1)(p + 5)
