1. a) i don't know what energy transformations which would apply.

Tungsten-filament lightbulb emits light based on the temperature of the filament. which phenomenon does this demonstrate?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?
