Calculate sound speed in hydrogen H2 at temperture 50 C degree. Answer give in meter per second.

irina [24]

Answer:

The speed of sound in hydrogen gas is 361.5 $^{\circ} C$

Explanation:

It is given that the temperature is 50 $^{\circ} C$ .

The speed of sound in meter per second is calculated by an equation.

The equation states that speed of the sound in meter per second is equal to the sum of the product of the temperature in degree celsius with 0.60 and a constant that is 331.5.

The equation is written as:

$speed \ of \ sound \left(m/s \right) = 0.60 \times T + 331.5$

Put the value of T = 50 then the equation becomes,

$speed \ of \ sound \left(m/s \right) = 0.60 \times 50 + 331.5$

Speed of sound (in m/s) = 361.5 m/s

Hypothermic body temperature can range from 28.7 °C to 35.5 °C. What is this range in degrees Fahrenheit?

Amanda [17]

Solution:

To convert Celsius to Fahrenheit, the formula to be used is (C * 9/5) + 32

So in our given, 28.7 degrees Celsius:

Farenheit = (28.7 * 9/5) + 32
= 51.66 + 32
= 83.66 degrees Fahrenheit

Next, 35.5 degrees Celsius:
Farenheit = (35.5 * 9/5) + 32
= 63.9 + 32
= 95.9 degrees Fahrenheit

So in Fahrenheit, the range would be 83.66 – 95.9 degrees Fahrenheit.
