Atest tube containing 35.5 g of lead shot (pb) is placed into a beaker containing deionized water(di h2o) at 25 degrees celsius. the test tube is removed 15 minutes after the water in the beaker has reached its boiling point (210 degrees fahrenheit). the lead is then gently transferred to a coffe-cup calorimeter containing 50.0g of di h2o at 22 degrees celsius. the temperature is observed to be 65.4 degrees celsius. determine the specific heat of lead and calculate the percent error

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

What’s #16 asking and how do i solve it?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
