What is heating and cooling curve? Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. What materials change when heated or cooled? We can change a material into its other states by heating it […]
What is the average kinetic energy of H2?
What is the average kinetic energy of H2? (b) What is the average kinetic energy of the H2(g) molecules? The average kinetic energy of the H2(g) molecules is 6.2 × 10−21 J because both gases are at the same temperature. Do all molecules have the same kinetic energy? Not all molecules will have the same […]

What is the life cycle of a cumulus cloud? Traditionally, a cloud lifetime is split into three phases: (1) a young cloud with a strong vertical growth; (2) a mature cloud, where the inflow of air from the subcloud thermal is assumed to be in balance with detrainment from the cloud into the environment; and […]

Can an elephant outrun a human?
Can an elephant outrun a human? Yes, elephants can run at 35-40kmph (25mph). Usain Bolt (the fastest man in the world was clocked at 37.383kmph. The short answer is no, humans cannot outrun elephants. A charging elephant can “run” much faster than you but if you zig-zag, you might be able to confuse it. Who […]
What are the four phases of self-regulation?
What are the four phases of self-regulation? According to Pintrich (2000) model, SRL is compounded by four phases: (1) Forethought, planning and activation; (2) Monitoring; (3) Control; and (4) Reaction and reflection. Each of them has four different areas for regulation: cognition, motivation/affect, behavior and context. What is the likely effect of Disidentification quizlet? What […]

Why Nitrogen is not a greenhouse gas?
Why Nitrogen is not a greenhouse gas? Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn’t change the electric field. In general, symmetrical molecules with only two atoms are not greenhouse gases. Why is sulfur dioxide not a greenhouse […]
