A) more than 30c
B) at or about 30c
C) less than 30c
The correct answer is A) more than 30c
The amount of water displaced by the block is the volume of the block. so (volume of water with block in it)-(original volume of water)= volume of block
This is the formula for finding calories: calories= (Tf-Ti)mass Or, in words, you subtract the final temperature (the temperature of the fused waters) by its initial temperature (the hot/ cold water's original temperature). You then multiply this answer by the mass of the water before you mix them together. Your hot and cold water should both have the same mass, but not the same temperature.
The weight of water displaced by the floating block of wood is exactly equal to the weight of the ENTIRE block of wood, regardless of how much of the wood is above the water level.
42.3 C
temperature of water. :) and youre welcome(:
The temperature of the metal bar decreases.The temperature of the cool water increases.The final temperature of the metal bar will be the same as the final temperature of the water.
Temperature of the water
The matter of the block displaced the water causing the water to rise
285C is above the boiling point of water at standard pressure. The block of copper will flash the water to steam, and the results of the experiment will be invalid.
You need to know the specific heat for copper. Then use q = mc∆T for copper and water. Heat lost by the copper MUST equal heat gained by the water. You can then solve for T2 of the water.
water
it will eventually become room temp
When allowed to stand for long enough, the final temperature will reach room temperature.
Measures the temperature of the water in your engine block, usually right where the water comes in from the radiator.
When allowed to stand for long enough, the final temperature will reach room temperature.
The brass needs to be immersed in the boiling water for a sufficient enough time that its temperature is the same as the boiling water, 100 degrees Celsius. That will be the initial temperature of the brass. After it is quickly placed in the calorimeter which will contain much cooler water, causing the brass to cool down and the water to heat up until the point where the temperature no longer changes. At that point the temperature of the brass is the same temperature as the water in the calorimeter, which is its final temperature of the brass.
You shouldn't be able to place a beetroot in water at a temperature of 0° C, because that is the temperature at which water freezes.
