Does aluminum have a higher specific heat capacity then lead?
no because the molar mass of lead is great than aluminum
What are four substances with a specific heat lower than water?
Almost any metal and many rocks/minerals; iron copper lead granite to name just four
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
A 38 kg block of lead is heated from 26 degrees Celsius to 180 degrees Celsius how much heat energy does the block of lead absorb to increase its temperature this much?
The specific heat of lead is 0.0305 K cal/kg deg C. The heat absorbed will be 38x(180-26)x0.0305 = 178.5 Kcal = 746.1 K joules
How can you remove lead from water?
The best way to remove lead and other metals from water is to pass the water over an ion exchange resin bed. Other ways include distillation but that requires quite a bit of heat energy input.
Does aluminum have a higher specific heat capacity then lead?
no because the molar mass of lead is great than aluminum
How much energy is needed to heat 0.5kg of Lead?
The specific heat (heat capacity) of lead is 26,65 J/mol.K; 64,31 J for heating 500 g with 1 K.
Does copper have a higher heat capacity than aluminum and iron and lead and zinc?
no
Does lead have a higher density than water?
yes

What quantities do you need to know in order to determine the amount of heat released by the lead sinker in cooling to the final temperature?
mass of water, initial temp of the water, final temp of water after the hot sinker is put into the water, the temp of the hot sinker (if it is heated in separate boiling water, the temperature of the water) and the specific heat of water ( 1 cal/g degree C)
Why is a hot water burn worse than a metal burn at the same temperature?
Part of it has to do with the difference in specific heat(the measure of the heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval), where water has a specific heat that is typically much higher than a given metal. Another part has to do with the fact that water is a liquid, meaning it can flow, and its adhesive(attraction between unlike molecules) properties that cause it to stick to your skin. So, the hot water stores more energy than the metal at the same temperature, and touching it causes it to stick to you, unlike metal which one can typically pull away from. These factors lead to a worse burn
What are the main features of a heat wave?
A heat wave is characterized by prolonged periods of excessively hot weather, typically with temperatures significantly above average for a specific region. Heat waves can lead to health risks such as heat exhaustion, dehydration, and heatstroke. They can also impact agriculture, water supply, and energy demand.
The heat capacity of a .287g lead sinker used by fishermen?
0.0367 Heat capacity depends on the material that it's made out of. If the sinker is made out of cast iron, it'd be around 0.46 kJ/kg K. Google "specific heat of metals" for lists.
Why does a kilogram of lead occupy a much smaller volume than a kilogram of water?
lead has much higher density
Why has gold got a higher specific gravity than lead when it has a lower atomic number mass?
13
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
