if a sample of wood and the same mass of water were placed in direct sunlight for 6 hours, which one will have a higher temperature change at the end of 6 hours? why? assume that they both absorb the same amount of energy (Hint refer to table 1)

A piece of metal was placed into a 75.00 grams of water.  The temperature of the water increased from 22.02 °C to 25.08  °C.  How much heat (in Joules) did the water absorb from the metal?  Do not type units into your answer.

Suppose object A has quadruple the specific heat and double the mass of object B. If the same amount of heat is applied to both objects, how will the temperature change of A be related to the temperature change of B? Enter your answer to three significant figures. Temperature change of A = i × (temperature change of B)

When a piece of aluminum weighing 52 grams, and at a temperature of 76.3 degrees C , is placed in a calorimeter containing 75.0 grams of water at 21.9 degrees C, the temperature of the water is increases to 28.3 degrees C. What is the specific heat of the calorimeter?

be sure your answer is correct and have the correct number of significant digits

A hot 122.8 g lump of an unknown substance initially at 154.8 °C is placed in 35.0 mL of water initially at 25.0 °C and the system is allowed to reach thermal equilibrium. The final temperature of the system is 56.9 °C. Using this information and the specific heat values for several metals in the table, identify the unknown substance. Assume no heat is lost to the surroundings. graphite zinc aluminum titanium tungsten rhodium Substance Specific heat (J/(g-°C)) aluminum 0.897 graphite 0.709 rhodium 0.243 titanium 0.523 0.132 0.388 4.184 tungsten zinc water

Suppose a boil water notice is sent out advising all residents in the area to boil their water before drinking it or using it for cooking. You need to boil 18.0 L of water using your natural gas (primarily methane) stove. What volume of natural gas is needed to boil the water if only 10.1% of the heat generated goes towards heating the water. Assume the density of methane is 0.668 g/L, the density of water is 1.00 g/mL, and that the water has an initial temperature of 21.4 °C. Enthalpy of formation values can be found in this table. Assume that gaseous water is formed in the combustion of methane.
