And ice cube Wayne 1 g is placed in our closed insulated container with 9 g of water at 20°C 68°F after 24 hours elapse the container will hold what
(1) ten grams of water
(2) one gram of ice and nine grams of water
(3) five grams of ice and five grams of water
(4) nine grams of ice and one gram of water
(5) ten grams of ice
Please translate into standard English:
"And ice cube Wayne 1 g "
Should there be a period after 68°F ? Should after begin with a capital letter?
Spelled wrong ice cube weighing and there should be a period
Thanks.
I think the ice cube will melt. What do you think?
So when a ice cube melts is it still one gram if it does the answer would be #1 wouldn't it
Yes, # 1.
I would go with #1 and the final T will be 10 C assuming the bucket doesn't "leak" heat.
To determine what the container will hold after 24 hours, we need to understand the process of heat transfer and the principles of energy conservation.
In this scenario, we have an ice cube that will be placed in a closed, insulated container along with 9 grams of water at 20°C (68°F). The ice cube has a mass of 1 gram. We need to consider the heat transfer between the ice cube and the water until they reach thermal equilibrium.
First, let's determine the initial energy content of the system. The specific heat capacity of water is approximately 4.18 J/g°C, and the specific latent heat of fusion (the heat required to convert 1 gram of ice into water at the same temperature) is approximately 334 J/g.
The initial energy content of the water can be calculated as:
Energy = mass × specific heat capacity × temperature change
Energy = 9 g × 4.18 J/g°C × (20°C - 0°C) = 753.6 J
The energy required to convert 1 gram of ice at 0°C to water at 0°C is:
Energy = mass × specific latent heat
Energy = 1 g × 334 J/g = 334 J
Now, the total energy in the system is 753.6 J + 334 J = 1087.6 J.
During the 24 hours, the ice cube will absorb heat from the water until they reach thermal equilibrium. This means that the energy gained by the ice cube will be equal to the energy lost by the water.
Since we have a closed, insulated container, there will be no heat exchange with the surroundings, and the total energy in the system will remain constant. Therefore, the total energy after 24 hours will still be 1087.6 J.
Now, let's consider the options:
(1) Ten grams of water: This option is incorrect because we cannot create additional water in the system; the total mass of water is already given as 9 grams.
(2) One gram of ice and nine grams of water: This option is incorrect as it implies that all the ice has melted and turned into water. However, the energy required to melt the ice is only 334 J, which is less than the initial energy of the system. Therefore, not all the ice will melt.
(3) Five grams of ice and five grams of water: This option is incorrect because it divides the total mass evenly. However, we know that not all the ice will melt, so the division of ice and water will not be equal.
(4) Nine grams of ice and one gram of water: This option seems plausible. As mentioned before, not all the ice will melt, so the majority of the ice will remain unchanged, and a small amount of water will be present.
(5) Ten grams of ice: This option is incorrect as it suggests that all the water will freeze completely, but we know that not all the ice will melt.
Therefore, the correct answer is option (4) - nine grams of ice and one gram of water.
