Aluminum has a higher specific heat capacity than iron. This means that for equal masses of aluminum and iron, the metal that heats more quickly when the same amount of heat is applied is   Question options: 1 need more information 2 iron. 3 aluminum.

I need help with this question

#1. What are the three mechanisms for heat transfer and how do they differ?

Problem 6:  Suppose you pour 0.0125 kg of 20.0°C water onto a 1.1-kg block of ice, sitting in a large bowl, which is initially at -15.0°C. The latent heat of fusion for water is Lf = 334 kJ/kg.   What is the final temperature of this system? You may assume that the water cools so rapidly that effects of the surroundings are negligible.

Two isolated systems with different temperatures are connected via long metal rod . The metal rod conducts heat between the two systems at a rate of 50 cals/s what will happen to the rate of the heat flow if the length of the metal rod is elongated 3 times the original distance as well as increasing the cross- sectional diameter by 3 times ? Round to one decimal place

0.4 kg water is at room temperature 23 degrees in an aluminum container. An unknown metal with 0.5 kg mass is placed inside the water raising its temperature to 40 degrees. A)What is the specific heat of the unknown metal. B) Would the equilibrium temperature greater, less or the same if the system was not properly isolated.

The temperature of 200 g of water increases from 20°C to 50°C in 10 minutes. Calculate:i.    the amount of heat gained by the water.   ii.    the average rate at which the water is gaining heat.                   (Specific heat capacity of water = 4200 J kg-1 OC-1)

On a cold day when a room temperature is 15oC, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15oC, because: A. metals have higher thermal capacity than plastics B. plastics have a lower density than metals C. metals are good conductor of heat D. plastics have a higher thermal conductivity than metals
