How does a heater in one corner of a fish aquarium warm the whole aquarium?
The heater warms the glass
The heater warms the air above
The heater adds thermal energy
The heater creates convection currents
I think that it is d am I right?
Yes, you are correct. The heater creates convection currents which circulate the warm air throughout the aquarium, warming the entire aquarium.

Yes, you are correct. The correct answer would be d) The heater creates convection currents.
When the heater is placed in one corner of the fish aquarium, it warms up the water in that area. As the water gets warmer, it expands and becomes less dense compared to the surrounding cooler water. This creates convection currents.
Convection is the process of heat transfer through the movement of a fluid (in this case, water). As the warm water rises due to reduced density, it displaces the cooler water, which then moves towards the heater to get warmed as well. This continuous circulation of water creates a cycle where heat is distributed throughout the entire aquarium.
The convection currents ensure that the warmth from the heater is distributed evenly throughout the fish tank, raising the overall temperature of the aquarium and keeping the fish in a comfortable environment.
