at which temperature does water have particles with a greater average kinetic energy than water with a temperature of 30°c?\n77°f\n95°f\n280k\n300k
Answer
Explanation:
Step1: Convert 30°C to Fahrenheit and Kelvin
Fahrenheit: $F = \frac{9}{5}C+ 32=\frac{9}{5}\times30 + 32= 86^{\circ}F$; Kelvin: $K = C + 273=30 + 273 = 303K$
Step2: Convert each option to the same - scale
- Option 1: $77^{\circ}F<86^{\circ}F$
- Option 2: For $95^{\circ}F$, $C=\frac{5}{9}(F - 32)=\frac{5}{9}(95 - 32)\approx35^{\circ}C>30^{\circ}C$
- Option 3: $280K<303K$
- Option 4: $300K<303K$
Answer:
B. $95^{\circ}F$
