hot air vents under the water
warming up by a space heater
a warm breeze in the air
pancakes cooking on a griddle
sun melting ice cream
touching a hot bench and it feels warm
burning your hand on a spoon in soup
a pot of water boiling
roasting marshmallows over a fire
Foot getting burned by hot sand
hot dogs cooking on a grill
enjoying the warmth of the sun at the beach
a hot air balloon rising
getting warm as you stand by a grill
hot air rising when the furnace blows
