A simple pendulum consists of a ball connected to one end of a thin brass wire. The period of the pendulum is 2.44 s. The temperature rises by 148 C°, and the length of the wire increases. What is the change in the period of the heated pendulum. [The coefficient of linear expansion for brass is, 19×10-6 (0C)-1]

The cavity within a copper [β = 51 × 10-6 (C°)-1] sphere has a volume of 1.200 × 10-3 m3. Into this cavity is placed 1.100 × 10-3 m3 of benzene [β = 1240 × 10-6 (C°)-1]. Both the copper and the benzene have the same temperature. By what amount ΔT should the temperature of the sphere and the benzene within it be increased, so that the liquid just begins to spill out?

A Cooper telephone wire has essentially no sag between poles 68m apart on winter day when the temperature is -20C. How much longer is the wire on a summer day when the temperature is 30.0C? Coefficient of linear expansion for copper is 1.70*10^5

A grandfather clock is controlled by a swinging brass pendulum that is 1.4 m long at a temperature of 27°C. (a) What is the length of the pendulum rod when the temperature drops to 0.0°C? (Give your answer to at least four significant figures.) mm (b) If a pendulum's period is given by T = 2√/L/g, where L is its length, does the change in length of the rod cause the clock to run fast or slow? O fast O slow Oneither

A shipment from Earth to Mars contains a 50 gallon​ [gal] tank filled with an ideal gas. The molecular weight of the ideal gas is 15.9 grams per mole​ [g/mol]. NASA tells the astronauts on Mars that the tank and gas combined had an initial total mass of 5 kilograms​ [kg] and the pressure was 3 atmospheres​ [atm] before it left the Earth. During the​ trip, the temperature was kept constant at 20 degrees Celsius ​[°​C]. When it arrives on​ Mars, the astronauts check the sensors and discover the pressure is 2.2 atmospheres​ [atm] and the temperature is 20 degrees Celsius ​[°​C]. Based on this​ information, the astronauts determine that some of the gas leaked during shipment. Determine how much gas leaked from the tank in units of grams​ [g]. Gravity on Mars​ = 3.71 meters per second squared​[m/s2​].

A fixed amount of an ideal gas is initially at a temperature of 25 °C. To what temperature you need to cool it down after you compress it to half of its volume if you want to keep the pressure constant? Give your answer in units of [Kelvin]

If a 0.69 km (at -12°C ) section of straight railroad track made of steel is assumed to behave as a single piece, what is the difference in the length of the track between a cold winter day (-12°C) and a hot summer day (+38°C)? The coefficient of linear expansion (α) of steel is 1.2 × 10-5 °C-1.[1 km = 1,000 m]
