Compare the room temperature resistances for all the samples. are they similar or different? the room temperature resistance should be much less for tin and lead. they behave like metals, and so have lower resistance.

Describe the difference between a. a hypothesis and a theory and b. an observation and an experiment.

Modern weaponry has increased the number of deaths in wars and violent conflicts.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
