    Physics, Chemistry and Biology: Post your doubts here!

    Alcohol: is made by fermentation using glucose, an anaerobic atmosphere and a temperature of 30 to 40 (I am not sure abt the temp) The above is for ethanol only I guess the others are made by the addition reaction of steam and the corresponding ethene....... (in chem) Bread: is made from a...

    I am sooo sorry for the delay, I just saw ur doubt now! Well, first measure x(s) and then calculate the scale by dividing 30 by the measured value of x Next use that scale and the measured value of y to calculate the real value (u can do that by multiplying the measured value of y by the scale)...

    Since they say that the temperature remains constant, P1V1 = P2V2 is used........... Now they have given us the pressure and volume of the helium in the cylinder and the pressure that normally is in the balloon What we have to calculate is the volume that will be present in the balloon at that...
