A person's body temperature is 1.05°F above normal. How many degrees above normal is their body temperature on the Celsius scale? HINT °C

Two 39.5-g ice cubes initially at 0°C are added to 460 g of water at 22.0°C. Assuming this system is insulated and ignoring heat transfer with the glass, what is the equilibrium temperature of the mixture? °C

You happen to come across a piece of metal that has a density of p = 7.43 g/cm³ when the temperature is To = 45.0 °C. If the metal is cooled to a temperature of T = 0.00 °C, does the density change? No, because as the volume changes so does the mass. No, density does not depend on temperature. Yes, since the metal contracts and the mass is constant, the density will increase. Yes, the density will decrease since the volume changes. Calculate the density of the piece of metal at this temperature, p1. The coefficient of volume expansion for this piece of metal is ß = 8.43 x 10-s 1°°C.

For each of the following temperatures, find the equivalent temperature on the indicated scale. (a) -206°C on the Fahrenheit scale °F (b) 99.4°F on the Celsius scale °C (c) 130 K on the Fahrenheit scale °F

€2 When an air bubble rises from the bottom to the top of a freshwater lake, its volume increases by 75%.

33. A bicycle tire has a pressure of 7.00 × 10° N/m² at a temperature of 18.0°C and contains 2.00 L of gas. What will its pressure be if you let out an amount of air that has a volume of 100 cm³ at atmospheric pressure? Assume tire temperature and volume remain constant.

A machinist wishes to insert a copper rod with a diameter of 8 mm into a hole with a diameter of 7.996 mm. By how much would the machinist have to lower the temperature (in °C) of the rod to make it fit the hole?  °C

A glass coffee pot has a 9.00 cm diameter circular bottom in contact with a heating element that keeps the coffee warm with a continuous 50.0-W heat input. (a) What is the temperature of the bottom of the pot, if it is 2.90 mm thick and the inside temperature is 67.8°C? The thermal conductivity of the pot is 0.84 J/(s · m · °C). *Answer in °C, please

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.

A fixed amount of a particular ideal gas at 20°C and a pressure of 1.75 × 105 Pa occupies a volume of 2.60 m3. If the volume is increased to 4.2 m³ and the temperature is raised to 27.0°C, what will be the new pressure (in Pa) of the gas? Pa
