1) Why the concept of the swing can be considered as an exothermic reaction? a) The friction between force exerted and the air create small amount of heat b) Endothermic reaction c) Endothermic reaction d) Because heat is absorbed from the surrounding and cause the ice cream to melt 2) A reaction that absorbs energy from surrounding a) Because heat is absorbed from the surrounding and cause the ice cream to melt b) Exothermic reaction c) Endothermic reaction d) The friction between force exerted and the air create small amount of heat 3) Picture above shows that a man is sweating after doing exercise in a playground? In your opinion, what is the type of reaction involved? a) Exothermic reaction b) Because heat is absorbed from the surrounding and cause the ice cream to melt c) The friction between force exerted and the air create small amount of heat d) Endothermic reaction 4) The usage of instant cold pack in playground is categorized under which reaction? a) Endothermic reaction b) Exothermic reaction c) Because heat is absorbed from the surrounding and cause the ice cream to melt d) The friction between force exerted and the air create small amount of heat 5) Why the melting ice cream is considered as endothermic reaction? a) Endothermic reaction b) The friction between force exerted and the air create small amount of heat c) Because heat is absorbed from the surrounding and cause the ice cream to melt d) Endothermic reaction
