HELP PLEASE!
1. In an alcohol-in-glass thermometer, the alcohol column has length 11.82 cm at 0.0°C and length 25.85 cm at 100.0°C.
(a) What is the temperature if the column has length 16.10 cm?
__°C
(b) What is the temperature if the column has length 21.00 cm?
__ °C
2.In an internal combustion engine, air at atmospheric pressure and a temperature of about 20°C is compressed in the cylinder by a piston to 1/3 of its original volume (compression ratio = 3.0). Estimate the temperature of the compressed air, assuming the pressure reaches 40 atm.
___ °C
3.How many moles of water are there in 2.700 L?
___moles
How many molecules?
___molecules
