Chapter 1: Problem 65

At what temperature is the temperature in degrees Fahrenheit equal to twice the temperature in degrees Celsius?

Short Answer

Expert verified
The temperature at which the temperature in degrees Fahrenheit is equal to twice the temperature in degrees Celsius is \(320^\circ\text{F}\).

Step by step solution

01

Write the formula for conversion between Celsius and Fahrenheit

The formula to convert Celsius to Fahrenheit is given by: \(F = \frac{9}{5}C + 32\), where F is the temperature in degrees Fahrenheit and C is the temperature in degrees Celsius.
02

Set up the equation

We are given that the temperature in degrees Fahrenheit (F) is equal to twice the temperature in degrees Celsius (2C). So, we can set up the equation: \(F = 2C\).
03

Substitute the conversion formula into the equation

Now, we will substitute the conversion formula from Step 1 into the equation from Step 2: \(\frac{9}{5}C + 32 = 2C\).
04

Solve for the temperature in Celsius

We will solve the equation for C to find the temperature in Celsius: \[\begin{aligned} \frac{9}{5}C + 32 &= 2C \\ \frac{9}{5}C - 2C &= -32 \\ \frac{-1}{5}C &= -32 \end{aligned} \] Now, we will multiply both sides by -5 to find the value of C: \[C = 160\]
05

Convert back to Fahrenheit

We found the temperature in Celsius at which Fahrenheit is twice the value of Celsius. Now, we will convert the Celsius value back to Fahrenheit using the formula from Step 1: \[F = \frac{9}{5}(160) + 32 = 320\] So, the temperature at which the temperature in degrees Fahrenheit is equal to twice the temperature in degrees Celsius is 320°F.

Science fiction often uses nautical analogies to describe space travel. If the starship U.S.S. Enterprise is traveling at warp factor \(1.71,\) what is its speed in knots and in miles per hour? (Warp \(1.71=5.00\) times the speed of light; speed of light = \(3.00 \times 10^{8} \mathrm{m} / \mathrm{s} ; 1\) knot \(=2030 \mathrm{yd} / \mathrm{h} .\) )

During a very cold winter, the temperature may remain below freezing for extended periods. However, fallen snow can still disappear, even though it cannot melt. This is possible because a solid can vaporize directly, without passing through the liquid state. Is this process (sublimation) a physical or a chemical change?

At room temperature the element bromine, \(\mathrm{Br}_{2},\) is a liquid with a density of 3.12 \(\mathrm{g} / \mathrm{cm}^{3} .\) Calculate the mass of 125 \(\mathrm{mL}\) of bromine. What volume does 85.0 \(\mathrm{g}\) of bromine occupy?

Perform the following mathematical operations, and express the result to the correct number of significant figures. a. \(6.022 \times 10^{23} \times 1.05 \times 10^{2}\) b. $\frac{6.6262 \times 10^{-34} \times 2.998 \times 10^{8}}{2.54 \times 10^{-9}}$ c. \(1.285 \times 10^{-2}+1.24 \times 10^{-3}+1.879 \times 10^{-1}\) d. \(\frac{(1.00866-1.00728)}{6.02205 \times 10^{23}}\) e. $\frac{9.875 \times 10^{2}-9.795 \times 10^{2}}{9.875 \times 10^{2}} \times 100(100 \text { is exact) }$ f. $\frac{9.42 \times 10^{2}+8.234 \times 10^{2}+1.625 \times 10^{3}}{3}(3 \text { is exact) }$

In a multiple-step calculation, is it better to round off the numbers to the correct number of significant figures in each step of the calculation or to round off only the final answer?
