I need some help. A helium balloon in a
closed car occupies a
volume of 7.7 liters at 68
degrees
Celsius. It's a hot day and
the temperature rises to 121
degrees Celsius, what is
the
new volume of the balloon?
Always convert
temperature to Kelvin:
(Celsius + 273 =
Kelvin)
A)-8.9 L
B)-09.5L
C)-07.7L
D)-8.2 L

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

fe 55.85 g/mol and h2o 18.02 g/mol.
