3. How does the vapor pressure of water at 10°C compare with its vapor pressure at 50°C? The vapor pressure of water is lower at

50°C than it is at 10°C. The vapor pressure of water is the same at 50°C as it is at 10°C The vapor pressure of water is greater at 50°C than it is at 10°C.

Answer :The vapor pressure of water is greater at 50°C than it is at 10°C.

Explanation: Vapor pressure is the pressure exerted by the vapors over the surface of the liquid.

Vapor pressure is directly proportional to the temperature as more is the temperature, more liquid can be converted to vapors and more vapors will exert greater vapor pressure.

As 50 ° C > 10 ° C, at 50 ° C, vapor pressure will be more as compared to 10 ° C.

The power is inversely proportional with time
trapecia [35]

Answer:

True

Explanation:

Given that Power whose unit is Watt equates to one joule of work per second. It implies that Power is directly proportional to the work done and inversely proportional to the time to do the work.

Therefore, in this case, the right answer to the question is that it is TRUE that the power is inversely proportional with time

A spherical snowball melts at a rate proportional to its surface area. (a) write a differential equation for its volume, v. (use
tresset_1 [31]

Answer:

Explanation:

The rate of change in volume is proportional to the surface area:

dV/dt = kA

Integrating:

V = kAt + C

At t=0, V = s, so:

s = kA(0) + C

C = s

Therefore:

V = kAt + s

A hotel wants to put a fence around a circular spa. The radius of the spa is 5/√2-1 feet. If the fence is built along the immedi
Vlad [161]
It is important to look at all the information's that are given in the question very closely. Let us write them write first.

Radius of the spa = <span>5/√2-1 feet
Now
Perimeter of the circle = </span><span>2πr
                                    = 2</span>π (5/√2-1) 
                                    = <span>π(5/(√2-1)*(√2+1)/(√2+1) </span>
<span>                                    = 2π(5/(√2+1))/(2-1) </span>
<span>                                    = 10π(√2+1)  

I hope that the procedure is clear enough for you to understand.</span>
