-0.00030 g/°C · cm3 x 25.1 °C.
Water density at 0 C is 0.999 g/cm3, and at 99 C it is 0.958 g/cm3, so why does ice float in hot water if ice is more dense that hot water.
A hot lump of 25.1 g of aluminum at an initial temperature of 86.7 °C is placed in 50.0 mL H, initially at 25.0 °C and allowed to reach thermal equilibrium. What is the final temperature of the aluminum and water, given that the specific heat of aluminum is 0.903 J/(g.°C)? Assume no heat is lost to surroundings. Tfinal °C
7. A coffee cup calorimeter contains 150 g of water at 25.1 °C. A 121 g block of solid copper is placed into the water and the temperature of the water and block goes to 30.1 °C. What was the perature of the copper block? The specific heat of solid copper metal is 0.385 J/g-°C and the specific heat of water is 4.184 J/g-°C. Assume that the calorimeter doesn't absorb any heat.
A silver block, initially at 58.6 ∘C, is submerged into 100.0 g of water at 25.1 ∘C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 27.3 ∘C. What is the mass of the silver block? I got 122.53g is it wrong?
24.9 and 25.1. Find the local linear approximation of the function f(x) = V14 + x at Xo = 11, and use it to approximate (a) S(x) = /14+x2 (b)/24.9 - (c) 25.1 - For parts (b) and (c), you should enter your answer as a fraction. If you enter a decimal, make sure that it is correct to at least six decimal places.
The density of ice near 0 C. is 0.917 g/cm3. If a 35 g ice cube floats on the surface of water (1.00 g/cm3), what volume of the ice is visible above the surface?
1.) Given the following densities at 25oC: magnesium: 1.7 g/cm3 graphite: 1.8 g/cm3 iron: 7.9 g/cm3 A block of iron has a mass of 625.0 g. What is the mass of a block of graphite that has the same volume as the block of iron? 110 g 2,120 g 4938g 142.4 483 g
11.0 g of aluminum at 200∘C and 22.0 g of copper are dropped into 44.0 cm3 of ethyl alcohol at 15.0∘C. The temperature quickly comes to 28.0 ∘C. What was the initial temperature of the copper in ∘C?
