Can someone explain why answer is three?
Cuz cicle allow light to pass through . Then since triangle same size as square. When an object is nearer to the light source . It wall cat a larger shadow thus blocking out the square

I suppose the human body is at 37c.... environment temp usually don't reach 37c....so if you want to feel cool u need to lose heat to surrounding....so u need fabric Y....but in a cold environment u need fabric X to keep warm

Concept tested here is that heat is transferred from object at higher temperature to object at lower temperature.
Body temperature is 37 deg C while surrounding normally lower. Hence body loses heat to surrounding.

Y is better conductor of heat, hence heat is lost at faster rate through Y.

--> Changes in states of matter (solid ,liquid and gas). Students are expected to know the structure of matter in their individual states as well.

### Re: Q&A - PSLE Science

This Q2 seems not set properly.
Magnet should be made of magnetic material. So (2) and (3) are both correct. Is my understanding correct?
