So i am doing a physics lab about the expansion of water. esentially i have a cork on a glass bottle filled with water. in two holes in the cork i have a pippette and then a go temperature probe to measure the temperature. the water is displaced into the pippette so i can measure the volume of expansion when the water heats up and cools. i first have to cool the water to 0 degrees and then have it in a room temperature room and record every mm expalnsion and the corresponding increase in temperature until 15 degrees. other than not accounting for the increase of expansion of the glass bottle, what other sources of error could there be for this experiment?

What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34

Which is an example of an exothermic process?

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
