Which step should be next in this procedure? List the materials that are needed. Write a conclusion for the experiment. Write a hypothesis for the results. Draw a table for the observations.

Light waves can move through , but they travel fastest when they move through a(n) .

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

One similarity and one difference between an element and a mixture of elements
