WebDec 18, 2024 · The required amount of steam for the system to reach a final temperature of 40.0°C is 7.2g.. The amount of steam required: According to the conservation of energy:. Heat lost by the steam = heat gained by water + heat gained by aluminum cup. The steam condenses to water at 100°C, so latent heat energy will also be involved.. Let m₁, m₂ … WebThe final temperature of the mixture is: a.) 100 C b.) 85.5 C c.) 79.5C d.) 74.5 C e.) 72.5 C This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: 10.)
what could be the final temperature of a mixture of 100 g of water …
WebDoes a cup of water at 50°C have twice as much thermal energy as an identical cup of water at 25°C? No, the hot water has only slightly more thermal energy. Suppose we are in the middle of a slowly melting block of ice. As we add a little more thermal energy, what happens to the temperature of the ice? The temperature remains constant. WebHow much heat is released as the temperature of 25.2 grams of iron is decreased from 72.1 °C to 9.8 °C? The specific heat of iron is 0.444 J/g • °C. 25.2 x 0.444 x 62.3 (72.1-9.8) = 0.697kJ What volume is occupied by 14.3 g of mercury? … cms hci
