High Blood Pressure :
It causes kidney failure because it pushes protien through glomerulus which leads to loss of filtiration power .
Low Blood Pressure :
It causes kidney failure because the shortage of oxygen in kidney leads to accumlation of waste products in kidney that poison it .

Take the oil in a test tube, and then put it in a water bath. Heat the water bath
But in this way the experiment wont be reliable . If wedirectly heat the water then we are not calculating the enrgy content rather the rise in tempreture of water is due to the bunsen burner flame
