7.400 cm3 of mercury at 0°C will expand to what volume at 50°C? Mercury has a volume expansion coefficient of 180X10-6/Cº. A) 450 cm3 B) 409.7 cm3 C) 403.6 cm3 D) 401.8 cm3
What is the change in length of a 30.0-cm-long column of mercury if its temperature changes from 37.0ºC to 40.0ºC , assuming the mercury is constrained in a tube so that the volume only changes in one dimension? (answer in ×10−6 m
The temperature on Mercury may drop to –169 °C at night. What is this temperature in Kelvin?
The temperature on Mercury may drop to −167 °C at night. What is this temperature in Kelvin?
What is the change in length in millimeters of a 3.00-cm-long column of mercury if its temperature changes from 37.0°C to 38.0°C, assuming the mercury is unconstrained lengthwise?
Question 10 2 pts If 15.5 J of heat are removed from 14.6 g of mercury (specific heat 0.142 J/g °C) at 25.0 °C, what is the final temperature of the mercury sample in °C? (Give only the numerical value in the box)
a)What is the change in length in millimeters of a 3.00-cm-long column of mercury if its temperature changes from 30.0°C to 46.0°C, assuming the mercury is unconstrained lengthwise? mm b)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 1.25 km high...
005 (part 1 of 2) 10.0 points The length of the column of mercury in a thermometer is 3 cm when the thermometer is immersed in ice water and 25 cm when the thermometer 1s immersed in boiled water. What should be the length at room tem perature of 22°C? Answer in units of cm 006 (part 2 of 2) 10.0 points If the mercury column is 25.2 cm long when the thermometer is immersed in a chemical solution, what...
Problem 2 (10 pts.) A. (5 pts.) The vapor pressure of mercury at 20°C is 160mPa. What is its vapor pressure at 50°C, given that its enthalpy of vaporization is 59.30kJ mol? B. (5 pts.) The normal boiling point of ethanol is 78.3 C and its molar enthalpy of vaporization is 39.3kJmol. What is the vapor pressure at 30 C
1. What would be the effect on the enthalpy change determined if the temperature probe read 1.0°C lower than the true temperature? Explain. (2 pts)
