The term "capacity of 900 joules" typically refers to the amount of energy that a system or object can store or deliver. In the context of thermal energy, it might indicate that a material can absorb or release 900 joules of heat. In other contexts, like batteries, it could signify the maximum energy the battery can store for use. Essentially, it quantifies the potential energy available in a given system.

How many joules of heat would be required to heat 0.5 kg of aluminum by 2k?
To calculate the heat required, we can use the formula ( Q = mc\Delta T ), where ( Q ) is the heat in joules, ( m ) is the mass in kg, ( c ) is the specific heat capacity of aluminum (approximately 900 J/kg·K), and ( \Delta T ) is the change in temperature in K. For 0.5 kg of aluminum heated by 2 K, the calculation is ( Q = 0.5 , \text{kg} \times 900 , \text{J/kg·K} \times 2 , \text{K} = 900 , \text{J} ). Therefore, 900 joules of heat would be required.
How do you convert mg into joules?
You cannot.A milligram is a measure of mass while a Joule is a measure of energy. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
How many joules of heat would be requiredto heat 0.5 kg of aluminum by 2k?
you need to know the specific heat capacity of aluminum first which can be denoted as 'c'. then using the formula: H=MC(dt) where 'dt; is the change in temperature, M is the mass and H is energy needed, you can thus calculate H. i think the value of 'c' for aluminum is around 0.88Jg/K Replace given values in the equation, you will surely get the answer!
What is heat capacity temperature measured in?
The heat capacity of a substance is typically measured in units of energy per degree Celsius (Joules per degree Celsius, J/C) or energy per Kelvin (Joules per Kelvin, J/K).
What is the specific heat capacity of water and alcohol?
The specific heat capacity of water is approximately 4.18 J/g°C, while the specific heat capacity of alcohol (ethanol) is around 2.44 J/g°C. This means it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius, and 2.44 Joules for 1 gram of alcohol.
What is meant by joule's constant?
joules constant
What is the unit of measure for water?
Mass = kg Volume = liter (pints and gallons and also quarts in the USA) Heat Capacity - Joules per Kg per Kelvin etc Is that what you meant?
If you do 900 joules of work in 10 minuteshow much power have you used?
10 joules of work in 1 second
What is water's heat capacity?
It is 4.184 Joules/g/deg.

How much is done when an 45 N forces moves a block 20 m?
The work done would be 900 joules. Work is calculated by multiplying the force applied (45 N) by the distance over which it is applied (20 m). This gives the work done in joules.
