Part C: Density of Water In this part, we will try to measure or calculate the density of water. As we have learnedin the lecture, the density of any matter will be the ratio of the mass of the given matterand the volume of the matter. We will have to obtain the data for the mass and the volumeof that given amount of water. We will use a rectangle container for this purpose. If we measurethe length, the width of the container, and if we pour the water in the container, we can calculatethe volume of the water. To get the mass of the water, we will measure the mass of the emptycontainer first, we will then measure the mass of the container with the water inside. The differenceof this two mass will be the net mass of the water that we are interested. We will do three trials. We will just put different amount of water in the container. Different amount of water will give you different height, but the length and the width of the container is the same. Since this…

A water droplet evaporates before they reach the ground. ond ord Figure 1: Water droplets [source] In this situation, a few assumptions are made: a) At initial point, a typical water droplet is in sphere shape with radius r and remain spherical while evaporating. b) The rate of evaporation (when it loses mass (m)) is proportional to the surface area, S. There is no air-resistance and downward direction is the positive direction. quat To describe this problem, given that p is the mass density of water, rois the radius of water before it drops, m is the water mass, V is the water volume andk is the constant of proportionality.
