To find the temperature at the core of the Sun, you consult someWeb sites on the Internet. One site says the temperature is about15 million °C, another says it is 15 million kelvin. Is this a seriousdiscrepancy? Explain.
Question 26
Suppose the sun was twice its current temperature. Recall, the sun is 7 x 105 km in
radius, with a surface temperature of 5800 K., and our distance from the sun is D =
150 million km. Using the equation to model the temperature of the earth,
(sun)1/4 Tsun and remembering you have to work in the absolute temperature
4D²
scale (OK = -273°C), what would happen to the temperature of the earth (in Kelvin
scale)?
It would be a quarter times as hot.
It would twice as hot.
It would be four times as hot.
It would be half as hot.
Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. We will estimate this effect in this problem, assuming the thermal coefficient of volume expansion is 210 × 10-6/°C for sea water.
1. Calculate the change in length, in meters, of a column of water 1.00 km high for a temperature increase of 1.00°C. Note that this calculation is only approximate because ocean warming is not uniform with depth. ΔL(in m)=
