4. your older brother announces that the lid to a jar of pickles from the refrigerator
is "impossible" to loosen. you take the jar, hold the lid under the hot water from
your sink's faucet for a few seconds, and calmly open the jar. your brother, when

knowledge of materials have you applied in this situation that really explains
how you were able to open the lid?

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 23.5c. 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)]
