Heating sample too rapidly may cause the thermometer reading to differ from the actual temperature of the heat source. Why is a finely powdered sample used in a melting point measurement? Particles may not pack well.

The attendence at a water park varies directly as the temperature and invesely as the number of days of rain during the month. I

Margarita [4]

Let A be attendance, t the temperature and n the number of days. Then,
A $\alpha$ $\frac{t}{n}$
A=k $\frac{t}{n}$
Where k is a constant of proportionality;
If A=3200, T=88 and n=8, then k,
3200= $\frac{88k}{8}$
3200=11k
k= $\frac{3200}{11}$
Rewriting the equation and replacing the value of k,
A= $\frac{3200t}{11n}$
When t=92 and n=12
The A= $\frac{3200*92}{11*12}$
A= $\frac{294400}{132}$
A= 2231
