Physics. Love it or Hate it.

Q17. The temperature of 1 kg of hydrgen gas is the same as that of 1 kg of helium gas if

A) the gases have the same internal energy
B) the gas molecules have the same root mean square speed
C) the gas molecules have the same mean translational kinetic energy
D) the gas molecules occupy equal volumes

The above is an MCQ Physics qn from a revered, elite junior college's Prelim Paper 2007. Don't worry, it's not from mine. It's probably the easiest question I would find in the whole MCQ paper already, yet the question is full of scientific jargons, which i'll totally forget in 6 months. Can you imagine tackling another 39 such questions for A's? In 1 hour 15 mins??? Well, I can and i did it (for my own prelims), and I have no idea how i survived it, suffice to say that it must have been by God's grace.

Physics is probably the easiest scoring paper ever, unless you're a math freak, cos math CAN be easy to score too. But physics is one subject I'll never really understand beneath it's A level's surface. Heck, I'm already having trouble trying to make sense of the syllabus. Anyway, physics is all about formulaes.. And when you put in some common sense, tada, there you've got the answer, without knowing how you did it. [this is how i feel most times when i'm doing physics! it's a terrible feeling, doing something you don't know!]

If you haven't made sense about what I'm trying to say, it's alright. At least now, you'll understand how i feel sometimes. The answer for the above qn is C, did you get/guessed that right?
