- Thank you!A 283 g silver figure of a polar bear is dropped into the 249 g aluminum cup of a well-insulated calorimeter containing 265 g of liquid water at 20.9°C. The bear's initial temperature is 98.5°C. What is the final temperature of the water, cup, and bear when they reach thermal equilibrium? The specific heats of silver, aluminum, and liquid water are, respectively, 234 J/ (kg-K), 910 J/ (kg-K), and 4190 J/ (kg-K). final temperature: °CSuppose due to a bad break of your femur, you require the insertion of a titanium rod to help the fracture heal. The coefficient of linear expansion for titanium is a-8.60-106 K and the length of the rod when it is in equilibrium with the leg bone and muscle at 37.0°C is 5.10 cm. How much shorter was the rod at room temperature (20.0°C)? um
- A hot air balloon holds 7.40 x 107 liters of gas. In order for the hot air balloon to rise into the sky, it must be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon to land. If the temperature of the balloon is decreased to 40.0°C, what will the new volume of the gas be? SOMEONE PLEASE HELP ME!!Though Babatunde's family take oats for breakfast, her mum decides that today they would take tea. She prepares it and serves Babatunde in an aluminium cup of mass 120 g. Before serving the tea, the cup had a temperature of 20 °C. The 0.30 kg tea that is poured into the cup is at a temperature of 70 °C. Determine the final temperature when thermal equilibrium is attained between the tea and the cup, assuming no exchange of heat with the surounding? (Cen is 4190 J/kg.
