Optimist1998:

As the pressure increases, the volume decreases leading to less space for them to move freely, with less space you get more friction [for gases]


But pressure has no effect on liquids
Which of the fluids are you referring to...... Gas or liquid?

Nuel25846:

u made that sound somehow erotic....especially the 'less space for them to move freely part' anyway it right.

Nuel25846:
In an ideal wheel an axle system, R
stand for the radius of the wheel and r is the radius of the axle. the
mechanical advantage is A. (R/r)2 B. r/R C. (r/R)2 D. R/r

Nuel25846:
The change in volume when 450kg of
ice is completely melted is [density of ice = 900 kgm -3, density of water = 100 kgm-3] A. 0.50m3 B. 0.45m3 C. 0.05m3 D. 4.50m3

A. 1 day
B. 2 days
C. 8 days
D. 24 days
E. 42 days.

How did past question arrive at 24

Nuel25846:

something like this I guess.

Nuel25846:

something like this I guess.

very correct.
Let me drop another method

Nuel25846:

its viscosity A. decreases B. increases C. increases then decreases D. remains constant

Optimist1998:
Wow your method is even better.
I calculated the area of the two triangles within the 2nd and 5th second then summed them up.

Nuel25846:
A 50W electric heater is used to heat
a metal block of mass 5kg. If in 10 minutes a temperature rise of 12oC is achieved, the specific heat capacity of
the metal is A. 400 J kg-1K-1 B. 500 J kg-1K-1 C. 390 J kg-1K-1 D. 130 J kg-1K-1

Donpre:

you could also relate two equations of motion

A. temperature is constant
B. pressure or volume is constant
C. concentration of products and reactants are same
D. all of above
