A rectangular plate of glass initially has the dimensions 0.200 m by 0.300 m. The coefficient of linear expansion for the glass is 9.00 * 10-6/K.What is the change in the plate’s area if its temperature is increased by 20.0 K?

A 200cm3 glass flask is filled to the brim with mercury (βHg= 18 x 10-5 K-1) at 20°C. How much mercury overflows when the temperature of the system is raised to 100°C? The coefficient of linear expansion of the glass is 0.40 x 10-5 K-1 A. 2.2cm³ B. 2.7cm³ C. 2.9cm³ D. 2.5cm³

= A steel rod with a length of I 1.55 m and a cross section of A = 3.04 cm² is held fixed at the end points of the rod. What is the size of the force developing inside the steel rod when its temperature is raised by AT = 25.0 K? The coefficient of linear expansion for steel is a = 1.17x10-5 1/K, and the Young modulus of steel is E = 200.0 GPa. Submit Answer Tries 0/12

You pour 998.00 cm3 of liquid mercury into a 1000.00 cm3-flask when both the mercury and the glass are at 4.0 ◦C. Determine the maximum temperature you can heat the system to (to the thousandth of a degree Celsius) before the mercury overflows. The mercury has a coefficient of volume expansion of 18.0 × 10−5◦C^−1 and the glass of the flask has a coefficient of volume expansion of 1.8 × 10−5◦C^ −1.

A metal rod has a starting length of 240 cm. When the temperature changes from 25 °C to 110 °C, the length of the rod changes 0.115 cm. What is the linear expansion coefficient of the rod?

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.

At a temperature of 22.00°C the hole in a steel plate has a diameter of 1.040 cm. If a steel rod with a diameter of 1.049 cm has to just slip through this hole, to what temperature should the plate be heated? The coefficient of area expansion of steel is 24 ✕ 10−6/°C. ________________________ °C
