I want to ask that there is a formula for km /h ?
Most of the time I notice that 5/18 is used.
For example 90 km/h = 90 × 5/18.
Please tell me why 5/18 is used.

Solution

To convert km/hr into m/sec :.
Let we have to convert x km/hr to m/s
since,
wwe know 1 km = 1000 m and 1 hr = 3600 s
So, x km/hr = 1000 x/ 3600 = 5/18 x

Determine the value of ∆H and ∆U for the reversible isothermal evaporation of 90.0g of water at 100°C. Assume that water vapour behave as am ideal gas and heat of eveporation of water is 540cal.

MY PROBLEM

Only tell me How ∆H is calculated here, because if I know∆H then I can use the equation

∆H = ∆U + nRT

In my book it is given that

∆H = 90.0 x 540

= 48600 cal

But I want to know that why they have multipled the mass to heat of eveporation to find out ∆H

Ramya wanted to arrange 90 barfi(with $1 \times 1$ dimension) in a box. She has 5 boxes of dimension $10 \times 9$ , $9 \times 10$ , $5 \times 18$ , $16 \times 5$ and $18 \times 5$ . Which box cannot be used to arrange all the barfis?
