When the tempature of a liquid in a closed container is decreased,?

1.when the specific heat capacity of the container is high, the temperature is acquired by the container from the liquid.
2.if the container is not properly protected with a insulating covering such as cotton or wool, there is heat loss by conduction.
3.if the container is not properly covered with a top lid, there is heat loss by convection.
4.if the container has no polished surfaces inside as well as outside, then there is heat loss by radiation.
