Calculate The Final Temperature Of The Granite

Increases in temperature tend to decrease density since volume will generally increase.

Calculate the final temperature of the granite.

Problem find the final temperature when 10 0 grams of aluminum at 130 0 c mixes with 200 0 grams of water at 25 c. What is the final temperature. M 1 mass kg c p 1 specific heat of substance j kg o c t 1 temperature o c m 2 mass kg c p 2 specific heat of substance j. Use the gizmo to mix 200 g of copper at 100 c with 1 000 g of water at 20 c.

This is the typical heat capacity of water. Use the specific heat capacity that you calculated for granite to determine how many grams of granite at the initial. Calculate the final temperature of the granite in celsius. Calculate the specific heat of nickel.

Start by calculating how much heat energy is needed to change the water s temperature by 0 45 c. Below is a table of units in which density is commonly expressed as well as the densities of some common materials. A 276 0 g piece of granite heated to 596 0 c in a campfire is dropped into 1 45 l water d 1 00 g ml at 25 0 c. 1 and can be used to calculate the final strike temperature when two liquids or solids or a liquid and a solid is mixed together.

You can also go to advanced mode to type the initial and final values of temperature manually. Determine the mass of the sample. Use the specific heat capacity that you calculated for granite to determine how many grams of granite at the initial temperature of 80 c must mix with 3 000 g of water at the initial temperature of 20 c to result in a final system temperature of 20 45 c. We will assume m 5 kg.

If the materials don t chemically react all you need to do to find the final temperature is to assume that both substances will eventually reach the same temperature. Calculate specific heat as c q mδt. There are exceptions however such as water s density increasing between 0 c and 4 c. 3 if 5750 j of energy are added to a 455 g piece of granite at 24 0 c what is the final temperature of the granite.

Use the gizmo to mix 200 g of granite at 100 c with 1 000 g of water at 20 c. The specific heat of granite is 0 803 j g c. What is the final temperature. The calculator below is based on eq.

2 when a 50 0 g piece of nickel absorbs 350 j of heat the temperature of the nickel changes from 20 c to 36 c.
