How do you calculate temperature change over time? Subtract the final and initial temperature to get the change in temperature (ΔT). Multiply the change in temperature with the mass of the sample. Divide the heat supplied/energy with the product. The formula is C = Q / (ΔT ⨉ m) . What is mean monthly temperature? […]
Why does hydrogen peroxide decompose slowly?
Why does hydrogen peroxide decompose slowly? Hydrogen peroxide has a finite shelf-life because, over time, it naturally decomposes into water and oxygen gas. Although this will take a while, UV rays from sunlight as well as warm conditions can actually catalyse the decomposition reaction. What happens to hydrogen peroxide when exposed to light? When exposed […]

Is the force of attraction between two objects?
Is the force of attraction between two objects? Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the […]
What is the biggest part of a comet?
What is the biggest part of a comet? nucleus What is the brightest part of a comet? comets head Why are comets green? When a comet gets warm enough, it creates an extended, gas-rich cloud known as a coma around its nucleus. If the coma contains carbon-nitrogen and carbon-carbon bonds, the Sun’s ultraviolet light will […]
Where do most action potentials originate?
Where do most action potentials originate? axon hillock Where do most action potentials begin quizlet? an action potential arrives at the synaptic terminal. calcium channels open, and calcium ions enter the synaptic terminal. vesicles containing neurotransmitter fuse with the plasma membrane of the sending neuron. neurotransmitter molecules diffuse across the synaptic cleft. What event triggers […]
Can ammonia be collected over water?
Can ammonia be collected over water? Ammonia gas is lighter than air and hence collected by the downward displacement of air. Ammonia is not collected over water because it is highly soluble in water. Why is ammonia not collected by downward delivery? Ammonia is more dense than air so it is collected by downward delivery. […]
