How many moles of gas are present if p=11 atm, v=12l, t=185k?

8.69 mol.

Explanation:

where, P is the pressure of the gas in atm (P = 11.0 atm).

V is the volume of the gas in L (V = 12.0 L).

n is the no. of moles of the gas in mol (n = ??? mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (T = 185.0 K).

∴ n = PV/RT = (11.0 atm)(12.0 L)/(0.0821 L.atm/mol.K)(185.0 K) = 8.69 mol.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
