See your other post. Same process.
To rank the following species according to the decreasing energy needed to raise the temperature of 10.0g of the substance by 25.0 degrees Celsius, we need to consider the specific heat capacity (also known as the heat capacity) of each substance.
The specific heat capacity (C) is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius. The formula to calculate the energy needed (Q) is Q = m * C * ΔT, where Q is the energy, m is the mass of the substance, C is the specific heat capacity, and ΔT is the change in temperature.
Now, let's find the specific heat capacity of each substance:
1. Copper - The specific heat capacity of copper is approximately 0.39 J/g·°C.
2. Aluminum - The specific heat capacity of aluminum is approximately 0.90 J/g·°C.
3. Cast iron - The specific heat capacity of cast iron can vary, but an average value is about 0.46 J/g·°C.
4. Silver - The specific heat capacity of silver is approximately 0.24 J/g·°C.
5. Water - The specific heat capacity of water is 4.18 J/g·°C.
Now, we can calculate the energy needed for each substance using the formula mentioned above:
1. Copper: Q = 10.0g * 0.39 J/g·°C * 25.0°C = 97.5 J
2. Aluminum: Q = 10.0g * 0.90 J/g·°C * 25.0°C = 225 J
3. Cast iron: Q = 10.0g * 0.46 J/g·°C * 25.0°C = 115 J
4. Silver: Q = 10.0g * 0.24 J/g·°C * 25.0°C = 60 J
5. Water: Q = 10.0g * 4.18 J/g·°C * 25.0°C = 1045 J
Therefore, from most to least energy needed to raise the temperature of 10.0g of the substance by 25.0 degrees Celsius, the ranking would be as follows:
1. Water
2. Aluminum
3. Cast iron
4. Copper
5. Silver
To rank the substances according to the decreasing energy needed to raise the temperature of 10.0g of the substance by 25.0 degrees Celsius, we need to consider the specific heat capacity of each material. The higher the specific heat capacity, the more energy is needed to raise the temperature of the substance.
Here are the ranks from most to least energy needed:
1. Water: Water has a high specific heat capacity, meaning it requires a significant amount of energy to raise the temperature. Therefore, water requires the most energy to raise the temperature of 10.0g by 25.0 degrees Celsius.
2. Copper: Copper has a lower specific heat capacity compared to water but higher than the remaining substances on the list. So, it requires the second most energy to raise the temperature of 10.0g by 25.0 degrees Celsius.
3. Aluminum: Aluminum has a lower specific heat capacity than copper, meaning it requires less energy to raise the temperature. Hence, it requires less energy than copper but more energy than cast iron and silver.
4. Cast iron: Cast iron has a lower specific heat capacity than both copper and aluminum, meaning it requires less energy to raise the temperature. Therefore, it requires less energy than the substances ranked above but more energy than silver.
5. Silver: Silver has the lowest specific heat capacity among the listed substances. Therefore, it requires the least amount of energy to raise the temperature of 10.0g by 25.0 degrees Celsius.
So, the final ranking from most to least energy needed is as follows:
1. Water
2. Copper
3. Aluminum
4. Cast iron
5. Silver
