FAQs

How do you calculate the temperature of water when mixed? The final temperature of a mixture of water can be calculated using the principle of conservation of energy, specifically the equation for heat transfer:

Q = m * c * ΔT

Where:

  • Q is the heat energy transferred.
  • m is the mass of the water.
  • c is the specific heat capacity of water.
  • ΔT is the change in temperature.

What would be the final temperature of a mixture of 100 g of water at 90°C and 600 g of water at 20°C? Assuming both waters have a specific heat capacity of approximately 4.18 J/g°C, you can use the heat transfer equation:

Tf = (m1 * c1 * T1 + m2 * c2 * T2) / (m1 * c1 + m2 * c2)

Tf = [(100 g * 4.18 J/g°C * 90°C) + (600 g * 4.18 J/g°C * 20°C)] / (100 g * 4.18 J/g°C + 600 g * 4.18 J/g°C)

Tf ≈ (37740 J + 50160 J) / (418 J + 2508 J) Tf ≈ 87900 J / 2926 J Tf ≈ 30°C

So, the final temperature of the mixture would be approximately 30°C.

To increase the duration of hot water, you may need a larger water heater or more efficient insulation.

What is the OSHA commercial hot water temperature regulations? OSHA (Occupational Safety and Health Administration) does not have specific regulations regarding commercial hot water temperature.

What is the final temperature of the mixture if 10g of ice at 10°C is mixed with 10g of water at 10°C? In this case, the ice will melt and reach the same temperature as the water, which is 10°C. This is because the energy required for the phase change (melting) comes from the heat of the water, causing the temperature to remain constant until all the ice has melted.

How much energy is needed to vaporize 10 grams of water at 100°C? To vaporize 10 grams of water at 100°C, you need to calculate the heat energy required for the phase change from liquid to vapor. The heat of vaporization for water is approximately 2260 J/g. So, the energy required would be:

Energy = mass * heat of vaporization Energy = 10 g * 2260 J/g = 22,600 J

How much heat energy is transferred when 10.0 grams of water at 50°C cools to 25°C? To calculate the heat energy transferred, you can use the heat transfer equation:

Q = m * c * ΔT

Where:

  • Q is the heat energy transferred.
  • m is the mass of water (10.0 g).
  • c is the specific heat capacity of water (approximately 4.18 J/g°C).
  • ΔT is the change in temperature (final temperature – initial temperature).

ΔT = 25°C – 50°C = -25°C

Q = 10.0 g * 4.18 J/g°C * (-25°C) = -1045 J

So, 1045 J of heat energy is transferred out of the water as it cools from 50°C to 25°C.

What is it called when two objects with different temperatures mix and eventually reach the same temperature? When two objects with different temperatures mix and eventually reach the same temperature, it is called thermal equilibrium. At thermal equilibrium, there is no net heat flow between the objects, and they have the same final temperature.

Is it possible for the temperature of two items to change by different degrees of temperature but change by the same amount of heat energy? Yes, it is possible for two items to change by different degrees of temperature but change by the same amount of heat energy. This can happen when the specific heat capacities of the two items are different. Specific heat capacity determines how much heat energy is required to change the temperature of a substance by a certain amount. Items with lower specific heat capacities will experience larger temperature changes for the same amount of heat energy transfer compared to items with higher specific heat capacities.

Is it OK to swim in 80 degree water? Swimming in 80-degree water can be comfortable for many people, especially in warm weather. However, individual preferences and tolerance to water temperature vary. It’s essential to be aware of your own comfort and safety while swimming, and always exercise caution in colder water, as it can lead to hypothermia if you stay in for an extended period.

How long can you survive in 85-degree water? Survival time in 85-degree water depends on various factors, including the individual’s physical condition, clothing, and activity level. In general, a person can survive for several hours in water at this temperature, but exhaustion and hypothermia can set in if not properly dressed or if exposed for an extended period.
