The properties of a closed system change following the relation between pressure and volume as p V = 3.0 where p is in bar V is in m3. Calculate the work done when the pressure increases from 1.5 bar to 7.5 bar.
An iron rod is 2.58m long at 0°C. Calculate the length of a brass rod at 0°C, if the difference between the lengths of the two rods must remain the same at all temperature. Linear expansivity of iron = 1.2 × 10^-5k^-1. Linear expansivity of brass = 1.9 × 10^-5k^-1
A particle mass m, traveling at a speed of v, strikes a stationary particle mass 2m. As a result the partucle of mass m, us deflected through an angle of 45 degrees at a speed of v/2. What is the speed and direction of mass 2m?

3.5 g of X reacts with a certain mass of Y to form a compound with 2 g of Y left over. 10.5 g of X reacts with a certain amount of Y to form the same compound of mass 42 g.
a. How much of Y combines with X to form the compound?
b. What is the chemical formula of the compound?
When a polar bear jumps on an iceberg, he notices that his 420 lb weight is just sufficient to sink the iceberg. What is the weight of the iceberg? Density of salt water is 64 lb/ft³ and that of iceberg is 57.2 lb/ft³.
solve this question. A body is weights first in the left and then in the right hand pan of a balance.the respective weights being 9.845grams and 9.836grams.calculate the true weight of the body and the ratio of the lenghts of the armths of the balance.
