Change in Volume Converting Ice to Water. To determine how much sea level would rise as a result of a given volume of ice melting, you first need to calculate the volume of water that would result from melting. Ice is less dense than water. It has a density that is 0.9 times (90%) that of water. Therefore, when one km3 of ice melts, it will decrease its volume by 10%. Thus, the conversion factor you need is: 1 km3 of ice = 0.9 km3 of water

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. provide a plausible explanation for this situation (with supporting calculations) by considering a room whose air temperature is maintained at 20â°c throughout the year, while the walls of the room are nominally at 27â°c and 14â°c in the summer and winter, respectively. the exposed surface of a person in the room may be assumed to be at a temperature of 32â°c throughout the year and to have an emissivity of 0.90. the coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 w/m2 â‹…â‹… k. what is the ratio of the thermal resistance due to convection to the thermal resistance due to radiation in the summer? what is the ratio of thermal resistances in the winter

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
