Calculate the specific heat capacity of the metal. J/(g·°C) oC C(water) = 4.18 J/(g·°C) e. What is the approximate molar mass of the...
Calculate the specific heat (J/g degree C) for each of the following: a. a 13.5-g sample of zinc (Zn) heated from 24.2 degree C to 83.6 degree C that absorbs 312 J of heat b. a 48.2-g sample of a metal that absorbs 345 J with a temperature increase from 35.0 degree C to 57.9 degree C
Copper has a specific heat of .390 j/gc. if 15.1 g of cu is heated to a tenoerature of 99.0 c and immersed in water. the resulting temperature of the cu was then 35.0. how much heat in j was transferred (added) to the water assume all heat us transferred to the water
Specific Heat (more precise) The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temparature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/mol- Degree C, and...
a. 100 J of heat energy are transferred to 20 g of mercury. By how much does the temperature increase? b. How much heat is needed to raise the temperature of 20 g of water by the same amount?
A 38.87 g sample of water (c = 4.18 J/gºC) is placed in a calorimeter with a heat capacity of 131.7 J/ºC. The heat of combustion of methane (CH4) is known to be 892 kJ/mole. According to the reaction below, how many grams of methane would be required to raise the temperature of the water sample 6.93ºC?
average specific heat = 0.694 J/g degres celcius a) A calorimeter contains 180.0 ml of water at 5.0°C. What is Tinal if a 55.00 g sample of your metal at 305.0°C is added? Use the average specific heat you measured. b) If a sample of your metal at 220.0°C causes a 120.0 ml sample of water to increase in temperature from 21.0°C to 24.3°C, what is mass of the metal? Use the average specific heat you measured. c) How much...
A 19 g sample of an alloy at 98.0°C is placed into 84.6 g of water at 22.0 °C in an insulated coffee cup with a heat capacity of 9.2 J/K. If the final temperature of the system is 35.0°C, what is the specific heat capacity of the alloy in J/(g.K)? Don't include units. cH2O = 4.184 J/g.K
A 56 gram sample of iron (with a heat capacity of 0.450 J/g ºC) is heated to 100.0 ºC. It is then transferred to a coffee cup calorimeter containing 40.35 g of water (specific heat of 4.184 J/ g ºC) initially at 20.63 ºC. If the final temperature of the system is 23.59, how much heat was absorbed by the calorimeter? Record your answer as a whole number (assume the sign is positive).
Path: P Words:0 QUESTION 27 A 42.9 g sample of Fe (specific heat 0.449 J/gºC) at an initial temperature of 125.0°C is added to 185.0 g sample of water. The final temperature reached for both is 42.1°C. Assuming no heat is lost to the surroundings and given that the specific heat of water is 4.18J/g°C, what is the initial temperature of the water, in °C? Simply type the number, not the unit.
