How does a thermos flask reduce heat loss by convection?
A vacuum between two glass sheets will greatly reduce heat loss through convection, and also through conduction. The fact that the glass is coated (to convert it to a mirror) also reduces the loss by radiation.
Does loft insulation reduce heat loss by conduction convection or radiation?
Insulation reduces heat loss by replacing air space with a less conductive material (insulation). Therefore the answer is conduction.
How does fleece reduce heat transfer by conduction and convection?
it reflects the heat back
The loss of body heat by conduction can be enhanced by?
Convection
How garments can be designed to reduce the transfer of heat by convection?
clothes can be made to reduce convection by making the air tighter so convection currents can't occur or if a material is shiny heat and light will reflect off it instead of absorbing it

What methods would you use to reduce heat loss from a cup of tea?
using different cups to reduce heat loss
Why does loft insulation reduse conduction and convection heat loss?
it eats it
What type of heat loss is reduced by cavity wall insulation?
convection
How does heat loss occur?
It can occur through conduction, convection and radiation.
