To express the temperatures of neon and carbon dioxide on the Celsius and Fahrenheit scales, we'll use the conversion formulas:

1. Celsius to Kelvin: K=°C+273.15K=°C+273.15
2. Kelvin to Fahrenheit: °F=(K−273.15)×95+32°F=(K−273.15)×59+32

Let's begin with Neon:

Neon's triple point temperature on the Kelvin scale is 24.57 K24.57K.

Converting this to Celsius: °C=24.57−273.15=−248.58°C°C=24.57−273.15=−248.58°C

Converting −248.58°C−248.58°C to Fahrenheit: °F=(−248.58)×95+32°F=(−248.58)×59+32 °F≈−415.44°F°F≈−415.44°F

Now, let's move on to Carbon Dioxide:

Carbon Dioxide's triple point temperature on the Kelvin scale is 216.55 K216.55K.

Converting this to Celsius: °C=216.55−273.15=−56.60°C°C=216.55−273.15=−56.60°C

Converting −56.60°C−56.60°C to Fahrenheit: °F=(−56.60)×95+32°F=(−56.60)×59+32 °F≈−69.88°F°F≈−69.88°F

So, Neon's triple point temperature on the Celsius scale is approximately −248.58°C−248.58°C or −415.44°F−415.44°F, and Carbon Dioxide's triple point temperature on the Celsius scale is approximately −56.60°C−56.60°C or −69.88°F−69.88°F.

Now, onto your question about absolute scales A and B. In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (solid, liquid, and gas) coexist in equilibrium. The triple point of water is a common reference point for temperature scales.

Given that the triple point of water is defined to be 200 on scale A and 350 on scale B, we can establish a relation between the two scales.

To find this relation, we can use the concept of linear interpolation. Since both scales measure temperature, we can assume a linear relationship between them.

Let TA be the temperature on scale A and TB be the temperature on scale B. We can set up a proportion:

(TA - 0) / (200 - 0) = (TB - 0) / (350 - 0)

Solving this proportion, we can find the relation between TA and TB. Let's do the math:

(TA - 0) / 200 = (TB - 0) / 350

TA / 200 = TB / 350

Cross-multiplying, we get:

TA * 350 = TB * 200

Dividing both sides by 350:

TA = (TB * 200) / 350

So, the relation between temperature on scale A (TA) and temperature on scale B (TB) is:

TA = (2/35) * TB

This equation provides a way to convert temperatures between the two scales. If you have a temperature in scale B and want to convert it to scale A, you can use this equation. Conversely, if you have a temperature in scale A and want to convert it to scale B, you would use the inverse of this equation.

For this problem, we're dealing with the relationship between electrical resistance and temperature, which is given by the formula:

R=R0[1+α(T−T0)]R=R0[1+α(T−T0)]

where:

• RR is the resistance at the given temperature TT,
• R0R0 is the resistance at a reference temperature T0T0,
• αα is the temperature coefficient of resistance, and
• TT is the temperature.

Given that the resistance at the triple point of water (T0=273.16 KT0=273.16K) is R0=101.6 ΩR0=101.6Ω and the resistance at the normal melting point of lead (T=600.5 KT=600.5K) is R=165.5 ΩR=165.5Ω, we can use these values to find the value of αα.

First, let's rearrange the equation to solve for αα:

α=R−R0R0(T−T0)α=R0(T−T0)R−R0

Substituting the given values:

α=165.5−101.6101.6×(600.5−273.16)α=101.6×(600.5−273.16)165.5−101.6

Now, we can find the value of αα.

Once we have αα, we can use it to find the temperature TT when the resistance is R=123.4 ΩR=123.4Ω. Rearranging the equation, we get:

T=T0+R−R0αR0T=T0+αR0R−R0

Substitute the given values into this equation to find the temperature corresponding to the resistance of 123.4 Ω123.4Ω.

The triple-point of water serves as a crucial standard fixed point in modern thermometry due to its unique properties. At this point, water coexists in equilibrium in its three phases: solid, liquid, and gas. This equilibrium ensures a precise and consistent temperature measurement, regardless of external conditions such as pressure.

Now, let's address why using the melting point of ice and the boiling point of water as standard fixed points, as originally done in the Celsius scale, may not be ideal. While these points are convenient and readily accessible, they are dependent on atmospheric pressure, which can vary significantly. This variability introduces uncertainty into temperature measurements, compromising their accuracy and reliability.

In contrast, the triple-point of water remains constant at a pressure of 611.657 pascals, or 0.0060373 standard atmospheres. By utilizing this fixed point, thermometers can be calibrated with precision, ensuring consistent and accurate temperature readings across different instruments and locations.

In summary, while the melting point of ice and the boiling point of water were suitable as standard fixed points in the past, the triple-point of water offers superior accuracy and consistency in modern thermometry, making it the preferred choice for calibrating temperature measurements.

In the Kelvin absolute scale, alongside the triple-point of water, the other fixed point corresponds to absolute zero. Absolute zero is the lowest possible temperature where particles cease to move, theoretically reaching a state of minimum entropy. This point is assigned the value of 0 Kelvin (0 K). So, to answer your question, the other fixed point on the Kelvin scale is absolute zero, which is 0 Kelvin (0 K).
