QUESTION 6 What is the relationship between the heat gained and the heat lost by the objects? A. The heat lost is greater then the heat gained. B. The heat gained is greater than the heat lost. C. The heat gained is equivalent to the heat lost. D. The heat gained and lost depend on the relative temperatures and therefore the relationship cannot be determined with the information given.

A coffee-cup calorimeter contains 130.0 g of water at 25.3 ∘C . A 124.0-g block of copper metal is heated to 100.4 ∘C by putting it in a beaker of boiling water. The specific heat of Cu(s) is 0.385 J/g⋅K . The Cu is added to the calorimeter, and after a time the contents of the cup reach a constant temperature of 30.3 ∘C . Part A Determine the amount of heat, in J , lost by the copper block....

PART A) A sample of metal at a known hot temperature is placed in to a calorimeter containing water of known mass and known initial temperature. The temperature of the water rises and the final temperature of the water is recorded. What equation is used to calculate the amount of heat the calorimeter water absorbed? PART B) How do you deermine the amount of heat lost by the metal if you know the amount of heat gained by the calorimeter...

SETUP In today’s lab we will measure specific heat using a calorimeter. A calorimeter consist of a small metal cup inside a larger metal container, with a lid.  The cups are thermally separated from each other by means of air and a wooden ring, thus reducing the thermal conduction to a minimum. To keep track of how much water etc. we have, the whole calorimeter will be placed on a digital scale. Make sure to zero the scale before you place...

A 220-g sample of copper is heated to 100∘∘C and placed into a cup containing 320 g of water initially at 30.0∘∘C. Ignore the container holding the water, assume no heat is lost or gained to the environment. 1) Find the final equilibrium temperature of the copper and water.

You have a block of ice at 32 degrees F, and a block of copper at some other temperature. The blocks have equal mass. Exactly the same amount of heat is added to each block. This causes the ice to melt completely, but not to warm up past 32 degrees F. The copper stays well below its melting point. How much does the copper expand? (Express your answer as a percentage, e.g. "the length of the copper increases by 1%.")...

How does the temperature and specific heat capacity of a sample of water (the calorimeter) change as a different mass or temperature of hot metal is added to it? How does the temperature and specific heat capacity of a sample of water (the calorimeter) change as the volume of water is changed? How does the molar enthalpy of dissolution change with the amount of substance added to water? How does the molar enthalpy of dissolution change with the volume of...
