How many joules released when 10 g of steam at 110 degrees cools to produce water at -5?
To calculate the energy released when the steam cools to water, you need to consider the specific heat capacity of water and steam. The equation Q = mcΔT can be used, where Q is the energy released, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Once you have the energy released, you can convert it to joules.

How many kilo joules of energy are released when 1.60 kg of water cools from 80.0 degrees Celsius to 60.0 degrees Celsius?
The specific heat capacity of water is 4.18 J/g°C. First, calculate the heat energy required to cool the water from 80.0°C to 60.0°C using the formula: q = mcΔT, where q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. Then, convert the heat energy from joules to kilojoules.
Is an air conditioner colder at 60 or 70?
An air conditioner does not have a specific temperature setting; rather, it cools the air to a desired temperature set by the user. Therefore, an air conditioner set to 60 degrees will produce colder air than one set to 70 degrees because it will cool the air to a lower temperature.
How much heat in kJ is given out when 85.0 g of lead cools from 200.0 C to 10.0 C?
To calculate the heat released, you can use the formula Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat capacity (0.128 J/g°C for lead), and ΔT is the temperature change. First, convert the mass to kilograms (85.0 g = 0.085 kg) and then calculate Q using the specific heat capacity of lead to get the answer in joules. Finally, convert joules to kilojoules (1 kJ = 1000 J) to find the heat released.
What is the density if water is cooled fron 4 degrees celcius to 0 degrees celcius?
The density of water increases as it cools from 4 degrees Celsius to 0 degrees Celsius. At 4 degrees Celsius, the density of water is 999.972 kg/m³, and at 0 degrees Celsius the density is 999.8395 kg/m³.
Describe the motion of the particle of a solid as it cools from -250 degrees Celsius to -273.15 degrees Celsius?
As the solid particle cools from -250 degrees Celsius to -273.15 degrees Celsius, the particles will lose kinetic energy and slow down, causing them to vibrate less and move closer together. At -273.15 degrees Celsius, the particles will reach absolute zero and stop all motion, resulting in a state of minimum energy and temperature known as absolute zero.
How many joules of energy are released when 45.0 g of water cools from 18.0 oC to 7.0 oC?

Does water that cools from 4 degrees celsius to 0 degrees celsius remain the same in density?
No, water's density decreases as it cools. Water reaches its maximum density at around 4 degrees Celsius, and as it cools further, the water molecules form a crystalline structure, causing the density to decrease.
Magma that cools quickly does it produce rocks that are fined grained?
Generally speaking, yes. Magma that cools quickly will produce small, "fine grained" crystals.Magma which cools slowly will generally produce rocks with larger, visible to the naked eye, crystals.This is because while magma is cooling, crystals are forming. Generally, crystal which have more time to grow will be larger. Therefore, generally, the slower magma cools, the bigger the crystals will be. The faster lava cools, the less time crystals have to grow and are thus smaller, "fine grained".
Is 25 degree Celsius considered cool?
25 degrees Celsius is typically considered comfortable or mild, but not cool. Cool temperatures are usually considered to be around 15-20 degrees Celsius.
What is a Comfortable pool temperature?
I like 85 degrees. It cools you and yet you don't get the shivers.
How many joules of heat are lost by 3580 kg of granite as its cools from 41.2 degreees Celsius to -12.9 degrees Celsius?
To calculate the heat lost, you need to use the formula: Q = mcΔT where: Q = heat lost m = mass of granite (3580 kg) c = specific heat capacity of granite (approx. 790 J/kg°C) ΔT = change in temperature (41.2 - (-12.9) = 54.1°C) Plug in the values and calculate to find the heat lost in joules.

How many joules are given off when 3.50kg of iron cools from 110 to 22?
To calculate the energy released when iron cools, we use the formula ( Q = mc\Delta T ), where ( m ) is the mass, ( c ) is the specific heat capacity of iron (approximately 450 J/kg·°C), and ( \Delta T ) is the change in temperature. Here, ( m = 3.50 , \text{kg} ), ( \Delta T = 110 - 22 = 88 , \text{°C} ). Thus, ( Q = 3.50 \times 450 \times 88 = 138600 , \text{J} ). Therefore, approximately 138,600 joules are given off.
