I hope it will helps paki brainliest na rin po thank you
Explanation:
1.)Now, I assume that this mass flux remains constant with time since the water is in thermal quasi-equilibrium with the room (a large temperature reservoir), and therefore remains at constant temperature, thus not changing the properties of water. The water takes 1.2 hours to fully evaporate.
2.)After evaporation of all liquid, I noticed some solid particles has formed in the evaporating dish these are the residue.
3.)Seawater is a complex mixture of 96.5% water, 2.5% salt and small amounts of other substances, including dissolved organic and inorganic materials, particles and some gases in the water. Seawater is a rich source of commercially important chemicals
4.)its like a half sphere shaped empty area where we put out foods especially soup.
5.)Brine is a homogeneous mixture or solution. Soil is made up of small pieces of many different materials, so it's a heterogeneous mixture. Water is a substance; more specifically, since water is composed of hydrogen and oxygen, it is a compound. Oxygen, a substance, is an element.
