How much heat in calories is needed to change 30 g of ice at -7 degrees celsius to water at 40 degrees celsius? A. 3000 cal B. 1214 cal. C. 3705 cal
How long does it take the Sun to melt a block of ice at 0∘C with a flat horizontal area 1.0 m2 and thickness 2.0 cm ? Assume that the Sun's rays make an angle of 45 ∘ with the vertical and that the emissivity of ice is 0.050. Express your answer using two significant figures.
Ice at -42 C was warmed to steam at 134 C. How much energy, in calories, was gained to warm 250 g of ice to steam? (get the sign right!) Specific heat H2O(g) = 0.48 cal/gram-C, Specific heat H2O(s) = 0.5 cal/gram-C. Specific heat H2O(l) = 1.0 cal/gram-C. Heat of vaporization H2O = 540 cal/gram, Heat of fusion H2O = 80 cal/gram.
How much heat does it take to turn 1g of O'C ice into 1g of 0°C water? 2256 J/kg 4.19 kg 3337 J/kg An aluminum block is wedged in a cavity inside a giant slab of very hard material, so that its volume cannot change. The aluminum block is the heated increasing the pressured the block Assume negligible heat flows into the cant slab Take the value of as 23106C and Bas 7010 Simplify the problem by solving it in...
A. How much heat energy, in kilojoules, is required to convert 68.0 g of ice at −18.0 ∘C to water at 25.0 ∘C ? Express your answer to three significant figures and include the appropriate units. B. How long would it take for 1.50 mol of water at 100.0 ∘C to be converted completely into steam if heat were added at a constant rate of 17.0 J/s ? Express your answer to three significant figures and include the appropriate units.
How much energy in kilojoules is needed to heat 5.30 g of ice from -10.0 ∘C to 27.5 ∘C? The heat of fusion of water is 6.01 kJ/mol, and the molar heat capacity is 36.6 J/(K⋅mol) for ice and 75.4 J/(K⋅mol) for liquid water. Please explain each step! Thank you!
