On a linear X temperature scale, water freezes at -101.0°X and boils at 415.0°X. On a linear Y temperature scale, water freezes at -78.00°Y and boils at -30.00°Y. A temperature of 57.00°Y corresponds to what temperature on the X scale? Number i Units

A superhero is building a suit of armor made of Vibranium (Vb). To mold the headpiece of this suit, he need to heat 1 kg of the metal into its forging temperature. Its forging temperature must be at least 70% of its melting point in Kelvin (MPyB = 3297 K). Assuming that the melting point and the forging temperature of Vb can be achieved, answer the following questions. a. Determine the specific heat capacity (J/kg-°C) of Vb if it loses 519.2775 kJ as it is being cooled from its melting point down to its forging temperature. b. The newly forged headpiece is then submerged in 2.5 L of liquid water initially at room temperature. Since the headpiece is still at its forging temperature right before it was submerged in water, some of the water vaporized in the process. What is the volume (L) of the remaining liquid water if the headpiece and the remaining water are in thermal equilibrium at 50 °C?

In an electrically heated home, the temperature of the ground in contact with a concrete basement wall is 11.9 °C. The temperature at the inside surface of the wall is 19.0 °C. The wall is 0.13 m thick and has an area of 7.5 m². Assume that one kilowatt hour of electrical energy costs $0.10. How many hours are required for one dollar's worth of energy to be conducted through the wall? Number i Units

An aluminum cup with mass 0.26 kg holds 0.30 kg of water. Both the cup and the water have a temperature of 15.°C. If a 0.55-kg piece of copper at 80.°C is added to the cup, what is the final equilibrium temperature in °C? You may assume that the cup, water, and copper are well insulated from anything else. (What can I do to solve this? What equations can I use?)

A 2-meter-long steel rod has a diameter equal to 2.54 cm. By how much does the rod’s length change in meters if it’s heated from 318 degrees Kelvin to 460 degrees Kelvin? _________ m . You should get a really small answer, feel free to use exponential notation to express it.
