- What mass of ice at -11.7°C is needed to cool a whale's water tank, holding 1.26 x 103 m3 of water, from 20.0°C down to a more comfortable 10.0°C?Final answer in decimal (like 0.0025 not 1.25x-0^-3). Unit for A is cm and B is C degree.You add 100.0 g of water at 50.1 °C to 100.0 g of ice at 0.00 °C. Some of the ice melts and cools the water to 0.00 °C. When the ice and water mixture reaches thermal equilibrium at 0 °C, how much ice has melted?
- If you have 0.251 m³ of water at 25.0 °C in an insulated container and add 0.112 m³ of water at 95.0 °C, what is the final temperature T; of the mixture? Use 1000 kg/m³ as the density of water at any temperature. °C Tf =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? °CWater at 16.0 °C is sprayed onto 0.230 kg of molten gold at 1063 °C (its melting point). The water boils away, forming steam at 100.0 °C and leaving solid gold at 1063 °C. What is the minimum mass of water that must be used? mw =
- Suppose 6.6 kg of chloroform at 24.4°C is poured into 6.6 kg of propylene glycol at 37°C. Calculate the final equilibrium temperature, neglecting any energy processes associated with mixing, given Cprop = 2500 J/(kg-K) and Cchloroform = 1050 J/(kg-K). T = °CSteam at 100°C is condensed into a 62.0 g brass calorimeter cup containing 220 g of water at 21.0°C. Determine the amount of steam (in g) needed for the system to reach a final temperature of 48.0°C. The specific heat of brass is 380 J/(kg · °C).1. Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 17 -L capacity when at 10 °C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95 °C operating temperature, given that the fluid's volume coefficient of expansion is ß= 400 ×10-6/°C? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95 °C. The volume coefficient of expansion of copper is 5.1 x 10-5/°C. Hint: Consider the expansions of both the fluid and the radiator. AV: L
