What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What is specific heat capacity equation?
Quantity of Energy= mass x temperature change x specific heat capacity For example: Find the amount of energy needed to raise the temperature of 0.20 kg of lead by 15 degree Celsius if the specific heat capacity of lead is 0.90 J/g degree Celsius. Answer: J=200g x 15 degree Celsius x 0.90 J/g degree Celsius = 2700 J
What is the formula for finding the final temperature in specific heat?
The formula for finding the final temperature in specific heat calculations is given by: [ T_f = T_i + \frac{Q}{m \cdot c} ] where (T_f) is the final temperature, (T_i) is the initial temperature, (Q) is the heat added or removed, (m) is the mass of the substance, and (c) is the specific heat capacity. This equation assumes no phase change occurs during the process.
What does it mean to say that a material has a high or low specific heat capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
In which temperature water has maximum specific heat capacity?
Water has the highest specific heat capacity at 25 degrees Celsius. This means that it can absorb or release a significant amount of heat before its temperature changes, making it an effective heat buffer.

For the specific heat capacity equation q equals m x C x Δt does change in temperature always have to be positive?
No, the change in temperature does not always have to be positive in the specific heat capacity equation. It can be positive if the temperature increases or negative if the temperature decreases. The sign of the change in temperature (Δt) will depend on whether heat is being added or removed from the system.
