A thermometer is taken from a room where the temperature is 25 C to the outdoors, where the temperature is -6 C. After one minute the thermometer reads 9 C. A) What will the reading on the thermometer be after 2 more minutes?
B) When will the thermometer read -5 C?

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. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
