To calculate the heat required to raise the temperature of water, you can use the formula: Q = m * c * ΔT, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. Plugging in the values, we get Q = 7.0 kg * 4.18 kJ/(kg°C) * (46°C - 25°C). Calculate this to find the heat energy required.

How much energy is required to raise water temp 1 degree Celsius?
The amount of energy required to raise the temperature of water by 1 degree Celsius is known as its specific heat capacity. For water, the specific heat capacity is 4.18 Joules/gram°C. This means that it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
What is the amount of heat needed to raise that temperature of 1 kilogram of water 1 degree Celsius?
The amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius is 4186 Joules, which is the specific heat capacity of water.
Name a substance that needs a lot of energy to raise its temperature?
Water is a substance that requires a lot of energy to raise its temperature because it has a high specific heat capacity. This means it can absorb a significant amount of heat energy before its temperature increases.
Why it takes more energy to raise the temperature of water than it does gold?
Water has a higher specific heat capacity than gold, meaning it requires more energy to raise its temperature. This is because water molecules can hold more heat energy due to their intermolecular structure compared to gold. As a result, more energy is needed to increase the kinetic energy of water molecules and raise the temperature of water.
How many kilowatts are required to raise the temperature of 1000 liters of water by 10 degrees centigrade?
To raise the temperature of 1000 liters of water by 10 degrees Celsius, you would require approximately 239 kilowatt-hours of energy. This can be calculated using the specific heat capacity of water and the formula for calculating energy required for temperature change.
Which liquid would be most difficult to raise or lower the temp of?
A liquid with a high specific heat capacity, such as water, would be the most difficult to raise or lower the temperature of because it can absorb or release a large amount of heat energy for a given change in temperature. Conversely, a liquid with a low specific heat capacity would be easier to raise or lower the temperature of.
Water has a temp of 4.184 and copper has a temp of 0.387. Does it takes more heat to raise the temp of the copper molecule?
Yes, it takes more heat to raise the temperature of copper than water because copper has a lower specific heat capacity than water. This means that it requires less heat to raise the temperature of water compared to copper for the same mass of the substance.

Is it harder to raise the temperature of a rock than it is to raise the temperature of water?
It is harder to raise the temperature of water than it is to raise the temperature of a rock. It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C, whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.
Does it take more energy as heat to raise the temperature of water by one degree than to raise the temperature of steam by the same amount?
Yes. The specific heat capacity of liquid water is 4.184 J/g•oC, and the specific heat capacity of steam is 2.010 J/g•oC.
Why it takes more energy to raise the temperature of water than it does gold?
