Why do electrons lose or gain electrons? Explanation: Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms). […]

What does the body use first for energy?
What does the body use first for energy? Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy […]

What happens to the particles when a liquid boils?
What happens to the particles when a liquid boils? Boiling. If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. As the liquid gets warmer more particles have sufficient energy to escape from the liquid. Eventually even particles in the middle of the liquid form bubbles […]
How high can a balloon go?
How high can a balloon go? Because density is altered by altitude, the helium balloon can reach a height of 9,000 meters, or 29,537 feet. Anything higher than this altitude will cause the helium within the balloon to expand and the balloon to pop. What is the common unbalanced force acting on an object in […]
What kind of mixture is salt solution and seawater?
What kind of mixture is salt solution and seawater? The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform. The difference is that the composition of the […]
Which out of the following is not an intensive property?
Which out of the following is not an intensive property? Volume is not an intensive property. Is pressure an intensive property? 1 Answer. You are right that intensive properties are not additive like the properties which depend on the extent of the system. Pressure is indeed an intensive property because it is force divided by […]
