Thanks..
Pranav-Arora said:You can look at it this way. When the aluminum rivets are emptied into that hole of ice, their temperature goes down to zero and during that process, energy is released which melts some of the ice. When the rivets are cooled down to zero, there is no further decrease in temperature and what you are left with is ice and the rivets at zero degrees.
CWatters said:1) If the block of ice is very big the final temperature of the rivets will be close to zero as all the energy in the hot rivets will be dissipated.
2) See the reply by rl.bhat and read up on the "specific heat capacity" of aluminium and the "Latent heat Capacity" of water/ice.
The specific heat capacity of aluminum rivets is approximately 0.897 J/g°C. This means that it takes 0.897 Joules of energy to raise the temperature of 1 gram of aluminum rivets by 1 degree Celsius.
Knowing the specific heat capacity of aluminum rivets is important for a variety of applications. It helps in determining the amount of heat needed to melt or weld aluminum rivets, as well as in calculating the heat transfer during various industrial processes.
The specific heat capacity of aluminum rivets is relatively low compared to other materials such as steel or copper. This means that aluminum rivets require less energy to heat up and cool down, making them a popular choice in industries where heat transfer is important.
Yes, the specific heat capacity of aluminum rivets is temperature dependent. As the temperature increases, the specific heat capacity also increases. This is due to the changing molecular structure of aluminum as it is heated.
The specific heat capacity of aluminum rivets can be measured using various techniques such as differential scanning calorimetry or calorimetry. These methods involve measuring the heat transfer and temperature change of a known quantity of aluminum rivets to calculate its specific heat capacity.
