I think you should try and use
q = mcT
where q = heat change
m = mass of substance
c = specific heat capacity of the substance ( Water is 4.187 kJmol-1)
T = change in temperature (oC)
so for your question,
q = mcT
q = 12 x 4.187 x (93-15.4)
q = 3898.9344 kJmol-1
Hope this helps!!

Why are land temperatures near water usually warmer?
Land temperatures near water are typically warmer due to the moderating effect of water on climate. Water has a high specific heat capacity, meaning it can absorb and store heat without a significant increase in temperature. As a result, during the day, water absorbs heat and releases it slowly at night, preventing rapid cooling and helping to maintain warmer temperatures in adjacent land areas. This phenomenon creates a more stable and moderate climate near bodies of water.
How does near water affect our temperature?
Near bodies of water, temperatures tend to be moderated due to the high specific heat capacity of water. This means that water can absorb and store heat during the day, preventing rapid temperature fluctuations. As a result, coastal areas often experience milder temperatures, with cooler summers and warmer winters compared to inland regions. This effect can create a more stable and pleasant climate for those living near water.
What temperature difference does it take to create convection currents in a water tank?
A temperature difference of around 20-30 degrees Fahrenheit is typically needed to generate significant convection currents in a water tank. As the water near the heat source heats up and becomes less dense, it rises, creating circulation within the tank.
Why does the ocean water near the equator absorbs more heat throughout the year than ocean water near the north pole?
Near the equator, the sun's angle of elevation (height above the horizon) is higher, making the sunlight more powerful.
What is lower near water?
The temperature is typically lower near water bodies, such as lakes or oceans, due to the cooling effect of the water. Water has a high specific heat capacity, meaning it absorbs and retains heat more effectively than land, leading to cooler air temperatures in its vicinity. Additionally, the presence of water can enhance humidity levels, which can also contribute to a cooler feeling in the surrounding area.
How does land and water absorb and release heat?
Land absorbs and releases heat faster than water due to its lower specific heat capacity. Specific heat is the amount of energy needed to raise the temperature of a substance by 1 degree Celsius. Water's higher specific heat allows it to absorb and release heat more slowly than land, which leads to more stable temperatures near water bodies.
How would heat transfer occur in water in a pot?
Heat transfer in water in a pot occurs through conduction, where heat moves from the burner to the pot, then from the pot to the water. As the water heats up, convection currents form, causing the hotter water near the bottom to rise and the cooler water near the top to sink, creating a circulating flow that helps distribute the heat throughout the water.
What is a sentence using oppressive?
The heat near the kiln was oppressive and the workers needed to get away from it occasionally.
Does convection heat a pan of water?
Yes, convection can heat a pan of water. As the water near the bottom of the pan absorbs heat, it becomes less dense and rises, creating a convection current that circulates the water and helps to distribute the heat evenly.
When you boil water the water near the stove burner becomes less what?
When you boil water, the water near the stove burner becomes less dense. This is because the water molecules absorb heat and become energized, causing them to move more rapidly and spread out, resulting in lower density near the heat source.
In water heat travels up much faster than it travels down Explain?
Heat travels faster in water when moving upwards because of the natural convection currents created by differences in water temperature. As water near the heat source warms up, it becomes less dense and rises, carrying heat with it. In contrast, heat traveling downwards must overcome the resistance of colder, denser water above, slowing down its transmission.
What tools do you use to see heat or extract?
it's called condensation, when the kettle is running and it's near a window you can see the heat on it. you are the tool no metals needed
Where does the heat that is needed to warm the surface of the ocean come from?
The heat that warms the surface of the ocean primarily comes from the sun, which radiates energy that is absorbed by the water. Additionally, heat can be transferred from the atmosphere to the ocean through processes like conduction and convection. Ocean currents also play a role in distributing heat throughout the water. Lastly, geothermal heat from the Earth's interior contributes to warming in specific areas, such as near hydrothermal vents.
Why was it so important for farmers to control the Huang river?
They had no irrigation and needed a near-by water source to water their crops.
How does living near a body of water impact air temperature?
Large bodies of water retain their heat (or lack of it) much longer than land; that is, they take longer to heat up, but stay warm longer. So, living near a lake or large river reduces or elevates the surrounding air tempurature. In the late summer, for instance, fog or mist is often seen over lakes and rivers in the early hours and into the morning, for the water is warmer than the air above it and that creates condensation.
How can being near a large body of water affect the climate of a region?
Being near a large body of water can moderate the climate of a region by providing a source of moisture and temperature regulation. Water has a high specific heat capacity, which means that it can absorb and release heat more slowly than land, leading to milder temperatures. Additionally, water bodies can influence wind patterns and create microclimates near their shores.
Why do they build their villages near water?
They built homes near the river because there were many resources near water. From fish to water to drink. Also if being attacked they would be able to get away easier if near water and could travel quickly and could avoid any enemies.
