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.
The final temperature will be closer to the original temperature of the water. Heat will flow from the water to the metal until they reach thermal equilibrium, resulting in a final temperature between the original temperatures of the two substances.
When ice is placed in a warm glass of water, the ice begins to melt as it absorbs heat energy from the water. This process continues until the ice has completely melted and the temperature of the water reaches equilibrium. The final temperature will be a combination of the initial temperature of the water and the melting point of the ice.
The matter of the block displaced the water causing the water to rise
The aluminum cube will lose heat as it cools down to the final temperature of the system. This heat will be transferred to the water causing it to increase in temperature. The final equilibrium temperature will be somewhere between the initial temperatures of the aluminum and water.
The heat lost by the copper block equals the heat gained by the water and calorimeter. Using the heat equation, q=mcΔT, where q is the heat, m is the mass, c is the specific heat, and ΔT is the change in temperature, you can calculate the final temperature of the system as 26.2 degrees Celsius.
The final temperature can be calculated using the principle of conservation of energy. The heat lost by the hot water will be equal to the heat gained by the ice as it melts and warms up. By using the specific heat capacities of water and ice, you can determine the final temperature of the system.
A block sinks when placed in water because its density is higher than the density of water. Since objects sink in water if they are denser than water, the force of gravity acting on the block is greater than the buoyant force pushing it up, causing it to sink.
water
The final temperature is 59.9°C.
Measures the temperature of the water in your engine block, usually right where the water comes in from the radiator.
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.
