(a) in an experiment, cold water is poured into a bowl made of an insulating material, the container
is placed in a draught-free room. After several hours, the volume and the temperature of the
water are found to have decreased.
Name and describe the process that causes the decrease in the volume of the water, and
explain why the temperature of the water decreases.

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
